Azure Identity client library for Python

The Azure Identity library provides Microsoft Entra ID (formerly Azure Active Directory) token authentication support across the Azure SDK. It provides a set of TokenCredential/SupportsTokenInfo implementations, which can be used to construct Azure SDK clients that support Microsoft Entra token authentication.

Source code | Package (PyPI) | Package (Conda) | API reference documentation | Microsoft Entra ID documentation

Getting started

Install the package

Install Azure Identity with pip:

pip install azure-identity

Prerequisites

  • An Azure subscription
  • Python 3.8 or a recent version of Python 3 (this library doesn't support end-of-life versions)

Authenticate during local development

When debugging and executing code locally, it's typical for developers to use their own accounts for authenticating calls to Azure services. The Azure Identity library supports authenticating through developer tools to simplify local development.

Authenticate via Visual Studio Code

Developers using Visual Studio Code can use the Azure Account extension to authenticate via the editor. Apps using DefaultAzureCredential or VisualStudioCodeCredential can then use this account to authenticate calls in their app when running locally.

To authenticate in Visual Studio Code, ensure the Azure Account extension is installed. Once installed, open the Command Palette and run the Azure: Sign In command.

It's a known issue that VisualStudioCodeCredential doesn't work with Azure Account extension versions newer than 0.9.11. A long-term fix to this problem is in progress. In the meantime, consider authenticating via the Azure CLI.

Authenticate via the Azure CLI

DefaultAzureCredential and AzureCliCredential can authenticate as the user signed in to the Azure CLI. To sign in to the Azure CLI, run az login. On a system with a default web browser, the Azure CLI launches the browser to authenticate a user.

When no default browser is available, az login uses the device code authentication flow. This flow can also be selected manually by running az login --use-device-code.

Authenticate via the Azure Developer CLI

Developers coding outside of an IDE can also use the Azure Developer CLI to authenticate. Applications using DefaultAzureCredential or AzureDeveloperCliCredential can then use this account to authenticate calls in their application when running locally.

To authenticate with the Azure Developer CLI, run the command azd auth login. For users running on a system with a default web browser, the Azure Developer CLI launches the browser to authenticate the user.

For systems without a default web browser, the azd auth login --use-device-code command uses the device code authentication flow.

Key concepts

Credentials

A credential is a class that contains or can obtain the data needed for a service client to authenticate requests. Service clients across the Azure SDK accept a credential instance when they're constructed, and use that credential to authenticate requests.

The Azure Identity library focuses on OAuth authentication with Microsoft Entra ID. It offers various credential classes capable of acquiring a Microsoft Entra access token. See the Credential classes section for a list of this library's credential classes.

DefaultAzureCredential

DefaultAzureCredential simplifies authentication while developing apps that deploy to Azure by combining credentials used in Azure hosting environments with credentials used in local development. For more information, see DefaultAzureCredential overview.

Continuation policy

As of version 1.14.0, DefaultAzureCredential attempts to authenticate with all developer credentials until one succeeds, regardless of any errors previous developer credentials experienced. For example, a developer credential may attempt to get a token and fail, so DefaultAzureCredential will continue to the next credential in the flow. Deployed service credentials stop the flow with a thrown exception if they're able to attempt token retrieval, but don't receive one. Prior to version 1.14.0, developer credentials would similarly stop the authentication flow if token retrieval failed, but this is no longer the case.

This allows for trying all of the developer credentials on your machine while having predictable deployed behavior.

Note about VisualStudioCodeCredential

Due to a known issue, VisualStudioCodeCredential has been removed from the DefaultAzureCredential token chain. When the issue is resolved in a future release, this change will be reverted.

Examples

The following examples are provided:

Authenticate with DefaultAzureCredential

More details on configuring your environment to use DefaultAzureCredential can be found in the class's reference documentation.

This example demonstrates authenticating the BlobServiceClient from the azure-storage-blob library using DefaultAzureCredential.

from azure.identity import DefaultAzureCredential
from azure.storage.blob import BlobServiceClient

default_credential = DefaultAzureCredential()

client = BlobServiceClient(account_url, credential=default_credential)

Enable interactive authentication with DefaultAzureCredential

By default, interactive authentication is disabled in DefaultAzureCredential and can be enabled with a keyword argument:

DefaultAzureCredential(exclude_interactive_browser_credential=False)

When enabled, DefaultAzureCredential falls back to interactively authenticating via the system's default web browser when no other credential is available.

Specify a user-assigned managed identity with DefaultAzureCredential

Many Azure hosts allow the assignment of a user-assigned managed identity. To configure DefaultAzureCredential to authenticate a user-assigned managed identity, use the managed_identity_client_id keyword argument:

DefaultAzureCredential(managed_identity_client_id=client_id)

Alternatively, set the environment variable AZURE_CLIENT_ID to the identity's client ID.

Define a custom authentication flow with ChainedTokenCredential

While DefaultAzureCredential is generally the quickest way to authenticate apps for Azure, you can create a customized chain of credentials to be considered. ChainedTokenCredential enables users to combine multiple credential instances to define a customized chain of credentials. For more information, see ChainedTokenCredential overview.

Async credentials

This library includes a set of async APIs. To use the async credentials in azure.identity.aio, you must first install an async transport, such as aiohttp. For more information, see azure-core documentation.

Async credentials should be closed when they're no longer needed. Each async credential is an async context manager and defines an async close method. For example:

from azure.identity.aio import DefaultAzureCredential

# call close when the credential is no longer needed
credential = DefaultAzureCredential()
...
await credential.close()

# alternatively, use the credential as an async context manager
credential = DefaultAzureCredential()
async with credential:
  ...

This example demonstrates authenticating the asynchronous SecretClient from azure-keyvault-secrets with an asynchronous credential.

from azure.identity.aio import DefaultAzureCredential
from azure.keyvault.secrets.aio import SecretClient

default_credential = DefaultAzureCredential()
client = SecretClient("https://my-vault.vault.azure.net", default_credential)

Managed identity support

Managed identity authentication is supported via either DefaultAzureCredential or ManagedIdentityCredential directly for the following Azure services:

Examples

These examples demonstrate authenticating SecretClient from the azure-keyvault-secrets library with ManagedIdentityCredential.

Authenticate with a user-assigned managed identity

To authenticate with a user-assigned managed identity, you must specify one of the following IDs for the managed identity.

Client ID
from azure.identity import ManagedIdentityCredential
from azure.keyvault.secrets import SecretClient

credential = ManagedIdentityCredential(client_id="managed_identity_client_id")
client = SecretClient("https://my-vault.vault.azure.net", credential)
Resource ID
from azure.identity import ManagedIdentityCredential
from azure.keyvault.secrets import SecretClient

resource_id = "/subscriptions/<id>/resourceGroups/<rg>/providers/Microsoft.ManagedIdentity/userAssignedIdentities/<mi-name>"

credential = ManagedIdentityCredential(identity_config={"resource_id": resource_id})
client = SecretClient("https://my-vault.vault.azure.net", credential)
Object ID
from azure.identity import ManagedIdentityCredential
from azure.keyvault.secrets import SecretClient

credential = ManagedIdentityCredential(identity_config={"object_id": "managed_identity_object_id"})
client = SecretClient("https://my-vault.vault.azure.net", credential)

Authenticate with a system-assigned managed identity

from azure.identity import ManagedIdentityCredential
from azure.keyvault.secrets import SecretClient

credential = ManagedIdentityCredential()
client = SecretClient("https://my-vault.vault.azure.net", credential)

Cloud configuration

Credentials default to authenticating to the Microsoft Entra endpoint for Azure Public Cloud. To access resources in other clouds, such as Azure Government or a private cloud, configure credentials with the authority argument. AzureAuthorityHosts defines authorities for well-known clouds:

from azure.identity import AzureAuthorityHosts

DefaultAzureCredential(authority=AzureAuthorityHosts.AZURE_GOVERNMENT)

If the authority for your cloud isn't listed in AzureAuthorityHosts, you can explicitly specify its URL:

DefaultAzureCredential(authority="https://login.partner.microsoftonline.cn")

As an alternative to specifying the authority argument, you can also set the AZURE_AUTHORITY_HOST environment variable to the URL of your cloud's authority. This approach is useful when configuring multiple credentials to authenticate to the same cloud:

AZURE_AUTHORITY_HOST=https://login.partner.microsoftonline.cn

Not all credentials require this configuration. Credentials that authenticate through a development tool, such as AzureCliCredential, use that tool's configuration. Similarly, VisualStudioCodeCredential accepts an authority argument but defaults to the authority matching VS Code's "Azure: Cloud" setting.

Environment variables

DefaultAzureCredential and EnvironmentCredential can be configured with environment variables. Each type of authentication requires values for specific variables:

Service principal with secret

Variable nameValue
AZURE_CLIENT_IDID of a Microsoft Entra application
AZURE_TENANT_IDID of the application's Microsoft Entra tenant
AZURE_CLIENT_SECRETone of the application's client secrets

Service principal with certificate

Variable nameValueRequired
AZURE_CLIENT_IDID of a Microsoft Entra applicationX
AZURE_TENANT_IDID of the application's Microsoft Entra tenantX
AZURE_CLIENT_CERTIFICATE_PATHpath to a PEM or PKCS12 certificate file including private keyX
AZURE_CLIENT_CERTIFICATE_PASSWORDpassword of the certificate file, if any
AZURE_CLIENT_SEND_CERTIFICATE_CHAINIf True, the credential sends the public certificate chain in the x5c header of each token request's JWT. This is required for Subject Name/Issuer (SNI) authentication. Defaults to False. There's a known limitation that async SNI authentication isn't supported.

Username and password

Variable nameValue
AZURE_CLIENT_IDID of a Microsoft Entra application
AZURE_USERNAMEa username (usually an email address)
AZURE_PASSWORDthat user's password

Configuration is attempted in the preceding order. For example, if values for a client secret and certificate are both present, the client secret is used.

Continuous Access Evaluation

As of version 1.14.0, accessing resources protected by Continuous Access Evaluation (CAE) is possible on a per-request basis. This behavior can be enabled by setting the enable_cae keyword argument to True in the credential's get_token method. CAE isn't supported for developer and managed identity credentials.

Token caching

Token caching is a feature provided by the Azure Identity library that allows apps to:

  • Cache tokens in memory (default) or on disk (opt-in).
  • Improve resilience and performance.
  • Reduce the number of requests made to Microsoft Entra ID to obtain access tokens.

The Azure Identity library offers both in-memory and persistent disk caching. For more information, see the token caching documentation.

Brokered authentication

An authentication broker is an application that runs on a user’s machine and manages the authentication handshakes and token maintenance for connected accounts. Currently, only the Windows Web Account Manager (WAM) is supported. To enable support, use the azure-identity-broker package. For details on authenticating using WAM, see the broker plugin documentation.

Troubleshooting

See the troubleshooting guide for details on how to diagnose various failure scenarios.

Error handling

Credentials raise CredentialUnavailableError when they're unable to attempt authentication because they lack required data or state. For example, EnvironmentCredential raises this exception when its configuration is incomplete.

Credentials raise azure.core.exceptions.ClientAuthenticationError when they fail to authenticate. ClientAuthenticationError has a message attribute, which describes why authentication failed. When raised by DefaultAzureCredential or ChainedTokenCredential, the message collects error messages from each credential in the chain.

For more information on handling specific Microsoft Entra ID errors, see the Microsoft Entra ID error code documentation.

Logging

This library uses the standard logging library for logging. Credentials log basic information, including HTTP sessions (URLs, headers, etc.) at INFO level. These log entries don't contain authentication secrets.

Detailed DEBUG-level logging, including request/response bodies and header values, isn't enabled by default. It can be enabled with the logging_enable argument. For example:

credential = DefaultAzureCredential(logging_enable=True)

CAUTION: DEBUG-level logs from credentials contain sensitive information. These logs must be protected to avoid compromising account security.

Next steps

Breaking Changes

These changes do not impact the API of stable versions such as 1.14.0. Only code written against a beta version such as 1.15.0b1 may be affected.

  • Windows Web Account Manager (WAM) Brokered Authentication is moved into another package.

Bugs Fixed

  • ManagedIdentityCredential will now correctly retry when the instance metadata endpoint returns a 410 response. (#32200)

1.14.1 (2023-10-09)

Bugs Fixed

  • Bug fixes for developer credentials

1.15.0b1 (2023-09-12)

Features Added

  • Added Windows Web Account Manager (WAM) Brokered Authentication support.
  • Added enable_msa_passthrough suppport for InteractiveBrowserCredential. By default InteractiveBrowserCredential only lists Microsoft Entra accounts. If you set enable_msa_passthrough to True, it lists both Microsoft Entra accounts and MSA outlook.com accounts that are logged in to Windows.

Bugs Fixed

  • Ensure AzurePowershellCredential calls PowerShell with the -NoProfile flag to avoid loading user profiles for more consistent behavior. (#31682)
  • Fixed an issue with subprocess-based developer credentials (such as AzureCliCredential) where the process would sometimes hang waiting for user input. (#31534)
  • Fixed an issue with ClientAssertionCredential not properly checking if CAE should be enabled. (#31544)
  • ManagedIdentityCredential will fall through to the next credential in the chain in the case that Docker Desktop returns a 403 response when attempting to access the IMDS endpoint. (#31824)

Other Changes

  • Update typing of async credentials to match the AsyncTokenCredential protocol.
  • If within DefaultAzureCredential, EnvironmentCredential will now use log level INFO instead of WARNING to inform users of an incomplete environment configuration. (#31814)
  • Strengthened AzureCliCredential and AzureDeveloperCliCredential error checking when determining if a user is logged in or not. Now, if an AADSTS error exists in the error, the full error message is propagated instead of a canned error message. (#30047)
  • ManagedIdentityCredential instances using IMDS will now be allowed to continue sending requests to the IMDS endpoint even after previous attempts failed. This is to prevent credential instances from potentially being permanently disabled after a temporary network failure.
  • IMDS endpoint probes in ManagedIdentityCredential will now only occur when inside a credential chain such as DefaultAzureCredential. This probe request timeout has been increased to 1 second from 0.3 seconds to reduce the likelihood of false negatives.

1.14.0 (2023-08-08)

Features Added

  • Continuous Access Evaluation (CAE) is now configurable per-request by setting the enable_cae keyword argument to True in get_token. This applies to user credentials and service principal credentials. (#30777)

Breaking Changes

  • CP1 client capabilities for CAE is no longer always-on by default for user credentials. This capability will now be configured as-needed in each get_token request by each SDK. (#30777)
    • Suffixes are now appended to persistent cache names to indicate whether CAE or non-CAE tokens are stored in the cache. This is to prevent CAE and non-CAE tokens from being mixed/overwritten in the same cache. This could potentially cause issues if you are trying to share the same cache between applications that are using different versions of the Azure Identity library as each application would be reading from a different cache file.
    • Since CAE is no longer always enabled for user-credentials, the AZURE_IDENTITY_DISABLE_CP1 environment variable is no longer supported.

Bugs Fixed

  • Credential types correctly implement azure-core's TokenCredential protocol. (#25175)

1.14.0b2 (2023-07-11)

Features Added

  • Added workload_identity_tenant_id support in DefaultAzureCredential.

1.14.0b1 (2023-06-06)

Features Added

  • Continue attempt next credential when finding an expired token from cached token credential in DefaultAzureCredential. (#30441)

Other Changes

  • VisualStudioCodeCredential prints an informative error message when used (as it is currently broken) (#30385)
  • Removed dependency on six. (#30613)

1.13.0 (2023-05-11)

Breaking Changes

These changes do not impact the API of stable versions such as 1.12.0. Only code written against a beta version such as 1.13.0b4 may be affected.

  • Windows Web Account Manager (WAM) Brokered Authentication is still in preview and not available in this release. It will be available in the next beta release.
  • Additional Continuous Access Evaluation (CAE) support for service principal credentials is still in preview and not available in this release. It will be available in the next beta release.
  • Renamed keyword argument developer_credential_timeout to process_timeout in DefaultAzureCredential to remain consistent with the other credentials that launch a subprocess to acquire tokens.

1.13.0b4 (2023-04-11)

Features Added

  • Credentials that are implemented via launching a subprocess to acquire tokens now have configurable timeouts using the process_timeout keyword argument. This addresses scenarios where these proceses can take longer than the current default timeout values. The affected credentials are AzureCliCredential, AzureDeveloperCliCredential, and AzurePowerShellCredential. (Note: For DefaultAzureCredential, the developer_credential_timeout keyword argument allows users to propagate this option to AzureCliCredential, AzureDeveloperCliCredential, and AzurePowerShellCredential in the authentication chain.) (#28290)

1.13.0b3 (2023-03-07)

Features Added

  • Changed parameter from instance_discovery to disable_instance_discovery to make it more explicit.
  • Service principal credentials now enable support for Continuous Access Evaluation (CAE). This indicates to Microsoft Entra ID that your application can handle CAE claims challenges.

1.13.0b2 (2023-02-07)

Features Added

  • Added AzureDeveloperCredential for Azure Developer CLI. (#27916)
  • Added WorkloadIdentityCredential for Workload Identity Federation on Kubernetes (#28536)
  • Added support to use "TryAutoDetect" as the value for AZURE_REGIONAL_AUTHORITY_NAME to enable auto detecting the appropriate authority (#526)

1.13.0b1 (2023-01-10)

Features Added

  • Added Windows Web Account Manager (WAM) Brokered Authentication support. (#23687)

Breaking Changes

These changes do not impact the API of stable versions such as 1.12.0. Only code written against a beta version such as 1.12.0b1 may be affected.

  • Replaced validate_authority with instance_discovery. Now instead of setting validate_authority=False to disable authority validation and instance discovery, you need to use instance_discovery=False.

Bugs Fixed

  • Fixed an issue where AzureCliCredential would return the wrong error message when the Azure CLI was not installed on non-English consoles. (#27965)

1.12.0 (2022-11-08)

Bugs Fixed

  • AzureCliCredential now works even when az prints warnings to stderr. (#26857) (thanks to @micromaomao for the contribution)
  • Fixed issue where user-supplied TokenCachePersistenceOptions weren't propagated when using SharedTokenCacheCredential (#26982)

Breaking Changes

  • Excluded VisualStudioCodeCredential from DefaultAzureCredential token chain by default as SDK authentication via Visual Studio Code is broken due to issue #23249. The VisualStudioCodeCredential will be re-enabled in the DefaultAzureCredential flow once a fix is in place. Issue #25713 tracks this. In the meantime Visual Studio Code users can authenticate their development environment using the Azure CLI.

Other Changes

  • Added Python 3.11 support and stopped supporting Python 3.6.

1.12.0b2 (2022-10-11)

1.12.0 release candidate

  • Added validate_authority support for msal client (#22625)

1.11.0 (2022-09-19)

Features Added

  • Added additionally_allowed_tenants to the following credential options to force explicit opt-in behavior for multi-tenant authentication:
    • AuthorizationCodeCredential
    • AzureCliCredential
    • AzurePowerShellCredential
    • CertificateCredential
    • ClientAssertionCredential
    • ClientSecretCredential
    • DefaultAzureCredential
    • OnBehalfOfCredential

  • Renamed argument name get_assertion to func for ClientAssertionCredential.

1.9.0b1 (2022-03-08)

Features Added

  • Added validate_authority support for msal client (#22625)
  • Added resource_id support for user-assigned managed identity (#22329)
  • Added ClientAssertionCredential support (#22328)
  • Updated App service API version to "2019-08-01" (#23034)

1.8.0 (2022-03-01)

Bugs Fixed

  • Handle injected "tenant_id" and "claims" (#23138)

    "tenant_id" argument in get_token() method is only supported by:

    • AuthorizationCodeCredential
    • AzureCliCredential
    • AzurePowerShellCredential
    • InteractiveBrowserCredential
    • DeviceCodeCredential
    • EnvironmentCredential
    • UsernamePasswordCredential

    it is ignored by other types of credentials.

Other Changes

1.7.1 (2021-11-09)

Bugs Fixed

  • Fix multi-tenant auth using async AadClient (#21289)

1.7.0 (2021-10-14)

Breaking Changes

These changes do not impact the API of stable versions such as 1.6.0. Only code written against a beta version such as 1.7.0b1 may be affected.

  • The allow_multitenant_authentication argument has been removed and the default behavior is now as if it were true. The multitenant authentication feature can be totally disabled by setting the environment variable AZURE_IDENTITY_DISABLE_MULTITENANTAUTH to True.
  • azure.identity.RegionalAuthority is removed.
  • regional_authority argument is removed for CertificateCredential and ClientSecretCredential.
  • AzureApplicationCredential is removed.
  • client_credential in the ctor of OnBehalfOfCredential is removed. Please use client_secret or client_certificate instead.
  • Make user_assertion in the ctor of OnBehalfOfCredential a keyword only argument.

1.7.0b4 (2021-09-09)

Features Added

  • CertificateCredential accepts certificates in PKCS12 format (#13540)
  • OnBehalfOfCredential supports the on-behalf-of authentication flow for accessing resources on behalf of users (#19308)
  • DefaultAzureCredential allows specifying the client ID of interactive browser via keyword argument interactive_browser_client_id (#20487)

Other Changes

  • Added context manager methods and close() to credentials in the azure.identity namespace. At the end of a with block, or when close() is called, these credentials close their underlying transport sessions. (#18798)

1.6.1 (2021-08-19)

Other Changes

  • Persistent cache implementations are now loaded on demand, enabling workarounds when importing transitive dependencies such as pywin32 fails (#19989)

1.7.0b3 (2021-08-10)

Breaking Changes

These changes do not impact the API of stable versions such as 1.6.0. Only code written against a beta version such as 1.7.0b1 may be affected.

  • Renamed AZURE_POD_IDENTITY_TOKEN_URL to AZURE_POD_IDENTITY_AUTHORITY_HOST. The value should now be a host, for example "http://169.254.169.254" (the default).

Bugs Fixed

  • Fixed import of azure.identity.aio.AzureApplicationCredential (#19943)

Other Changes

  • Added CustomHookPolicy to credential HTTP pipelines. This allows applications to initialize credentials with raw_request_hook and raw_response_hook keyword arguments. The value of these arguments should be a callback taking a PipelineRequest and PipelineResponse, respectively. For example: ManagedIdentityCredential(raw_request_hook=lambda request: print(request.http_request.url))
  • Reduced redundant ChainedTokenCredential and DefaultAzureCredential logging. On Python 3.7+, credentials invoked by these classes now log debug rather than info messages. (#18972)
  • Persistent cache implementations are now loaded on demand, enabling workarounds when importing transitive dependencies such as pywin32 fails (#19989)

1.7.0b2 (2021-07-08)

Features Added

  • InteractiveBrowserCredential keyword argument login_hint enables pre-filling the username/email address field on the login page (#19225)
  • AzureApplicationCredential, a default credential chain for applications deployed to Azure (#19309)

Bugs Fixed

  • azure.identity.aio.ManagedIdentityCredential is an async context manager that closes its underlying transport session at the end of a with block

Other Changes

  • Most credentials can use tenant ID values returned from authentication challenges, enabling them to request tokens from the correct tenant. This behavior is optional and controlled by a new keyword argument, allow_multitenant_authentication. (#19300)
    • When allow_multitenant_authentication is False, which is the default, a credential will raise ClientAuthenticationError when its configured tenant doesn't match the tenant specified for a token request. This may be a different exception than was raised by prior versions of the credential. To maintain the prior behavior, set environment variable AZURE_IDENTITY_ENABLE_LEGACY_TENANT_SELECTION to "True".
  • CertificateCredential and ClientSecretCredential support regional STS on Azure VMs by either keyword argument regional_authority or environment variable AZURE_REGIONAL_AUTHORITY_NAME. See azure.identity.RegionalAuthority for possible values. (#19301)
  • Upgraded minimum azure-core version to 1.11.0 and minimum msal version to 1.12.0
  • After IMDS authentication fails, ManagedIdentityCredential raises consistent error messages and uses raise from to propagate inner exceptions (#19423)

1.7.0b1 (2021-06-08)

Beginning with this release, this library requires Python 2.7 or 3.6+.

Added

  • VisualStudioCodeCredential gets its default tenant and authority configuration from VS Code user settings (#14808)

1.6.0 (2021-05-13)

This is the last version to support Python 3.5. The next version will require Python 2.7 or 3.6+.

Added

  • AzurePowerShellCredential authenticates as the identity logged in to Azure PowerShell. This credential is part of DefaultAzureCredential by default but can be disabled by a keyword argument: DefaultAzureCredential(exclude_powershell_credential=True) (#17341)

Fixed

  • AzureCliCredential raises CredentialUnavailableError when the CLI times out, and kills timed out subprocesses
  • Reduced retry delay for ManagedIdentityCredential on Azure VMs

1.6.0b3 (2021-04-06)

Breaking Changes

These changes do not impact the API of stable versions such as 1.5.0. Only code written against a beta version such as 1.6.0b1 may be affected.

  • Removed property AuthenticationRequiredError.error_details

Fixed

  • Credentials consistently retry token requests after connection failures, or when instructed to by a Retry-After header
  • ManagedIdentityCredential caches tokens correctly

Added

  • InteractiveBrowserCredential functions in more WSL environments (#17615)

1.6.0b2 (2021-03-09)

Breaking Changes

These changes do not impact the API of stable versions such as 1.5.0. Only code written against a beta version such as 1.6.0b1 may be affected.

  • Renamed CertificateCredential keyword argument certificate_bytes to certificate_data

  • Credentials accepting keyword arguments allow_unencrypted_cache and enable_persistent_cache to configure persistent caching accept a cache_persistence_options argument instead whose value should be an instance of TokenCachePersistenceOptions. For example:

    # before (e.g. in 1.6.0b1):
DeviceCodeCredential(enable_persistent_cache=True, allow_unencrypted_cache=True)

# after:
cache_options = TokenCachePersistenceOptions(allow_unencrypted_storage=True)
DeviceCodeCredential(cache_persistence_options=cache_options)

    See the documentation and samples for more details.

Added

  • New class TokenCachePersistenceOptions configures persistent caching
  • The AuthenticationRequiredError.claims property provides any additional claims required by a user credential's authenticate() method

1.6.0b1 (2021-02-09)

Changed

  • Raised minimum msal version to 1.7.0
  • Raised minimum six version to 1.12.0

Added

  • InteractiveBrowserCredential uses PKCE internally to protect authorization codes
  • CertificateCredential can load a certificate from bytes instead of a file path. To provide a certificate as bytes, use the keyword argument certificate_bytes instead of certificate_path, for example: CertificateCredential(tenant_id, client_id, certificate_bytes=cert_bytes) (#14055)
  • User credentials support Continuous Access Evaluation (CAE)
  • Application authentication APIs from 1.5.0b2

Fixed

  • ManagedIdentityCredential correctly parses responses from the current (preview) version of Azure ML managed identity (#15361)

1.5.0 (2020-11-11)

Breaking Changes

  • Renamed optional CertificateCredential keyword argument send_certificate (added in 1.5.0b1) to send_certificate_chain
  • Removed user authentication APIs added in prior betas. These will be reintroduced in 1.6.0b1. Passing the keyword arguments below generally won't cause a runtime error, but the arguments have no effect. (#14601)
    • Removed authenticate method from DeviceCodeCredential, InteractiveBrowserCredential, and UsernamePasswordCredential
    • Removed allow_unencrypted_cache and enable_persistent_cache keyword arguments from CertificateCredential, ClientSecretCredential, DeviceCodeCredential, InteractiveBrowserCredential, and UsernamePasswordCredential
    • Removed disable_automatic_authentication keyword argument from DeviceCodeCredential and InteractiveBrowserCredential
    • Removed allow_unencrypted_cache keyword argument from SharedTokenCacheCredential
    • Removed classes AuthenticationRecord and AuthenticationRequiredError
  • Removed identity_config keyword argument from ManagedIdentityCredential (was added in 1.5.0b1)

Changed

  • DeviceCodeCredential parameter client_id is now optional. When not provided, the credential will authenticate users to an Azure development application. (#14354)
  • Credentials raise ValueError when constructed with tenant IDs containing invalid characters (#14821)
  • Raised minimum msal version to 1.6.0

Added

  • ManagedIdentityCredential supports Service Fabric (#12705) and Azure Arc (#12702)

Fixed

  • Prevent VisualStudioCodeCredential using invalid authentication data when no user is signed in to Visual Studio Code (#14438)
  • ManagedIdentityCredential uses the API version supported by Azure Functions on Linux consumption hosting plans (#14670)
  • InteractiveBrowserCredential.get_token() raises a clearer error message when it times out waiting for a user to authenticate on Python 2.7 (#14773)

1.5.0b2 (2020-10-07)

Fixed

  • AzureCliCredential.get_token correctly sets token expiration time, preventing clients from using expired tokens (#14345)

Changed

  • Adopted msal-extensions 0.3.0 (#13107)

1.4.1 (2020-10-07)

Fixed

  • AzureCliCredential.get_token correctly sets token expiration time, preventing clients from using expired tokens (#14345)

1.5.0b1 (2020-09-08)

Added

  • Application authentication APIs from 1.4.0b7
  • ManagedIdentityCredential supports the latest version of App Service (#11346)
  • DefaultAzureCredential allows specifying the client ID of a user-assigned managed identity via keyword argument managed_identity_client_id (#12991)
  • CertificateCredential supports Subject Name/Issuer authentication when created with send_certificate=True. The async CertificateCredential (azure.identity.aio.CertificateCredential) will support this in a future version. (#10816)
  • Credentials in azure.identity support ADFS authorities, excepting VisualStudioCodeCredential. To configure a credential for this, configure the credential with authority and tenant_id="adfs" keyword arguments, for example ClientSecretCredential(authority="<your ADFS URI>", tenant_id="adfs"). Async credentials (those in azure.identity.aio) will support ADFS in a future release. (#12696)
  • InteractiveBrowserCredential keyword argument redirect_uri enables authentication with a user-specified application having a custom redirect URI (#13344)

Breaking changes

  • Removed authentication_record keyword argument from the async SharedTokenCacheCredential, i.e. azure.identity.aio.SharedTokenCacheCredential

1.4.0 (2020-08-10)

Added

  • DefaultAzureCredential uses the value of environment variable AZURE_CLIENT_ID to configure a user-assigned managed identity. (#10931)

Breaking Changes

  • Renamed VSCodeCredential to VisualStudioCodeCredential
  • Removed application authentication APIs added in 1.4.0 beta versions. These will be reintroduced in 1.5.0b1. Passing the keyword arguments below generally won't cause a runtime error, but the arguments have no effect.
    • Removed authenticate method from DeviceCodeCredential, InteractiveBrowserCredential, and UsernamePasswordCredential
    • Removed allow_unencrypted_cache and enable_persistent_cache keyword arguments from CertificateCredential, ClientSecretCredential, DeviceCodeCredential, InteractiveBrowserCredential, and UsernamePasswordCredential
    • Removed disable_automatic_authentication keyword argument from DeviceCodeCredential and InteractiveBrowserCredential
    • Removed allow_unencrypted_cache keyword argument from SharedTokenCacheCredential
    • Removed classes AuthenticationRecord and AuthenticationRequiredError
    • Removed identity_config keyword argument from ManagedIdentityCredential

1.4.0b7 (2020-07-22)

  • DefaultAzureCredential has a new optional keyword argument, visual_studio_code_tenant_id, which sets the tenant the credential should authenticate in when authenticating as the Azure user signed in to Visual Studio Code.
  • Renamed AuthenticationRecord.deserialize positional parameter json_string to data.

1.4.0b6 (2020-07-07)

  • AzureCliCredential no longer raises an exception due to unexpected output from the CLI when run by PyCharm (thanks @NVolcz) (#11362)
  • Upgraded minimum msal version to 1.3.0
  • The async AzureCliCredential correctly invokes /bin/sh (#12048)

1.4.0b5 (2020-06-12)

  • Prevent an error on importing AzureCliCredential on Windows caused by a bug in old versions of Python 3.6 (this bug was fixed in Python 3.6.5). (#12014)
  • SharedTokenCacheCredential.get_token raises ValueError instead of ClientAuthenticationError when called with no scopes. (#11553)

1.4.0b4 (2020-06-09)

  • ManagedIdentityCredential can configure a user-assigned identity using any identifier supported by the current hosting environment. To specify an identity by its client ID, continue using the client_id argument. To specify an identity by any other ID, use the identity_config argument, for example: ManagedIdentityCredential(identity_config={"object_id": ".."}) (#10989)
  • CertificateCredential and ClientSecretCredential can optionally store access tokens they acquire in a persistent cache. To enable this, construct the credential with enable_persistent_cache=True. On Linux, the persistent cache requires libsecret and pygobject. If these are unavailable or unusable (e.g. in an SSH session), loading the persistent cache will raise an error. You may optionally configure the credential to fall back to an unencrypted cache by constructing it with keyword argument allow_unencrypted_cache=True. (#11347)
  • AzureCliCredential raises CredentialUnavailableError when no user is logged in to the Azure CLI. (#11819)
  • AzureCliCredential and VSCodeCredential, which enable authenticating as the identity signed in to the Azure CLI and Visual Studio Code, respectively, can be imported from azure.identity and azure.identity.aio.
  • azure.identity.aio.AuthorizationCodeCredential.get_token() no longer accepts optional keyword arguments executor or loop. Prior versions of the method didn't use these correctly, provoking exceptions, and internal changes in this version have made them obsolete.
  • InteractiveBrowserCredential raises CredentialUnavailableError when it can't start an HTTP server on localhost. (#11665)
  • When constructing DefaultAzureCredential, you can now configure a tenant ID for InteractiveBrowserCredential. When none is specified, the credential authenticates users in their home tenants. To specify a different tenant, use the keyword argument interactive_browser_tenant_id, or set the environment variable AZURE_TENANT_ID. (#11548)
  • SharedTokenCacheCredential can be initialized with an AuthenticationRecord provided by a user credential. (#11448)
  • The user authentication API added to DeviceCodeCredential and InteractiveBrowserCredential in 1.4.0b3 is available on UsernamePasswordCredential as well. (#11449)
  • The optional persistent cache for DeviceCodeCredential and InteractiveBrowserCredential added in 1.4.0b3 is now available on Linux and macOS as well as Windows. (#11134)
    • On Linux, the persistent cache requires libsecret and pygobject. If these are unavailable, or libsecret is unusable (e.g. in an SSH session), loading the persistent cache will raise an error. You may optionally configure the credential to fall back to an unencrypted cache by constructing it with keyword argument allow_unencrypted_cache=True.

1.4.0b3 (2020-05-04)

  • EnvironmentCredential correctly initializes UsernamePasswordCredential with the value of AZURE_TENANT_ID (#11127)
  • Values for the constructor keyword argument authority and AZURE_AUTHORITY_HOST may optionally specify an "https" scheme. For example, "https://login.microsoftonline.us" and "login.microsoftonline.us" are both valid. (#10819)
  • First preview of new API for authenticating users with DeviceCodeCredential and InteractiveBrowserCredential (#10612)
    • new method authenticate interactively authenticates a user, returns a serializable AuthenticationRecord
    • new constructor keyword arguments
      • authentication_record enables initializing a credential with an AuthenticationRecord from a prior authentication
      • disable_automatic_authentication=True configures the credential to raise AuthenticationRequiredError when interactive authentication is necessary to acquire a token rather than immediately begin that authentication
      • enable_persistent_cache=True configures these credentials to use a persistent cache on supported platforms (in this release, Windows only). By default they cache in memory only.
  • Now DefaultAzureCredential can authenticate with the identity signed in to Visual Studio Code's Azure extension. (#10472)

1.4.0b2 (2020-04-06)

  • After an instance of DefaultAzureCredential successfully authenticates, it uses the same authentication method for every subsequent token request. This makes subsequent requests more efficient, and prevents unexpected changes of authentication method. (#10349)
  • All get_token methods consistently require at least one scope argument, raising an error when none is passed. Although get_token() may sometimes have succeeded in prior versions, it couldn't do so consistently because its behavior was undefined, and dependened on the credential's type and internal state. (#10243)
  • SharedTokenCacheCredential raises CredentialUnavailableError when the cache is available but contains ambiguous or insufficient information. This causes ChainedTokenCredential to correctly try the next credential in the chain. (#10631)
  • The host of the Active Directory endpoint credentials should use can be set in the environment variable AZURE_AUTHORITY_HOST. See azure.identity.KnownAuthorities for a list of common values. (#8094)

1.3.1 (2020-03-30)

  • ManagedIdentityCredential raises CredentialUnavailableError when no identity is configured for an IMDS endpoint. This causes ChainedTokenCredential to correctly try the next credential in the chain. (#10488)

1.4.0b1 (2020-03-10)

  • DefaultAzureCredential can now authenticate using the identity logged in to the Azure CLI, unless explicitly disabled with a keyword argument: DefaultAzureCredential(exclude_cli_credential=True) (#10092)

1.3.0 (2020-02-11)

  • Correctly parse token expiration time on Windows App Service (#9393)
  • Credentials raise CredentialUnavailableError when they can't attempt to authenticate due to missing data or state (#9372)
  • CertificateCredential supports password-protected private keys (#9434)

1.2.0 (2020-01-14)

  • All credential pipelines include ProxyPolicy (#8945)
  • Async credentials are async context managers and have an async close method (#9090)

1.1.0 (2019-11-27)

  • Constructing DefaultAzureCredential no longer raises ImportError on Python 3.8 on Windows (8294)
  • InteractiveBrowserCredential raises when unable to open a web browser (8465)
  • InteractiveBrowserCredential prompts for account selection (8470)
  • The credentials composing DefaultAzureCredential are configurable by keyword arguments (8514)
  • SharedTokenCacheCredential accepts an optional tenant_id keyword argument (8689)

1.0.1 (2019-11-05)

  • ClientCertificateCredential uses application and tenant IDs correctly (8315)
  • InteractiveBrowserCredential properly caches tokens (8352)
  • Adopted msal 1.0.0 and msal-extensions 0.1.3 (8359)

1.0.0 (2019-10-29)

Breaking changes:

  • Async credentials now default to aiohttp for transport but the library does not require it as a dependency because the async API is optional. To use async credentials, please install aiohttp or see azure-core documentation for information about customizing the transport.
  • Renamed ClientSecretCredential parameter "secret" to "client_secret"
  • All credentials with tenant_id and client_id positional parameters now accept them in that order
  • Changes to InteractiveBrowserCredential parameters
    • positional parameter client_id is now an optional keyword argument. If no value is provided, the Azure CLI's client ID will be used.
    • Optional keyword argument tenant renamed tenant_id
  • Changes to DeviceCodeCredential
    • optional positional parameter prompt_callback is now a keyword argument
    • prompt_callback's third argument is now a datetime representing the expiration time of the device code
    • optional keyword argument tenant renamed tenant_id
  • Changes to ManagedIdentityCredential
    • now accepts no positional arguments, and only one keyword argument: client_id
    • transport configuration is now done through keyword arguments as described in azure-core documentation

Fixes and improvements:

  • Authenticating with a single sign-on shared with other Microsoft applications only requires a username when multiple users have signed in (#8095)
  • DefaultAzureCredential accepts an authority keyword argument, enabling its use in national clouds (#8154)

Dependency changes

1.0.0b4 (2019-10-07)

New features:

  • AuthorizationCodeCredential authenticates with a previously obtained authorization code. See Microsoft Entra's authorization code documentation for more information about this authentication flow.
  • Multi-cloud support: client credentials accept the authority of an Azure Active Directory authentication endpoint as an authority keyword argument. Known authorities are defined in azure.identity.KnownAuthorities. The default authority is for Azure Public Cloud, login.microsoftonline.com (KnownAuthorities.AZURE_PUBLIC_CLOUD). An application running in Azure Government would use KnownAuthorities.AZURE_GOVERNMENT instead:
from azure.identity import DefaultAzureCredential, KnownAuthorities
credential = DefaultAzureCredential(authority=KnownAuthorities.AZURE_GOVERNMENT)

Breaking changes:

  • Removed client_secret parameter from InteractiveBrowserCredential

Fixes and improvements:

  • UsernamePasswordCredential correctly handles environment configuration with no tenant information (#7260)
  • user realm discovery requests are sent through credential pipelines (#7260)

1.0.0b3 (2019-09-10)

New features:

  • SharedTokenCacheCredential authenticates with tokens stored in a local cache shared by Microsoft applications. This enables Azure SDK clients to authenticate silently after you've signed in to Visual Studio 2019, for example. DefaultAzureCredential includes SharedTokenCacheCredential when the shared cache is available, and environment variable AZURE_USERNAME is set. See the README for more information.

Dependency changes:

1.0.0b2 (2019-08-05)

Breaking changes:

  • Removed azure.core.Configuration from the public API in preparation for a revamped configuration API. Static create_config methods have been renamed _create_config, and will be removed in a future release.

Dependency changes:

  • Adopted azure-core 1.0.0b2
    • If you later want to revert to a version requiring azure-core 1.0.0b1, of this or another Azure SDK library, you must explicitly install azure-core 1.0.0b1 as well. For example: pip install azure-core==1.0.0b1 azure-identity==1.0.0b1
  • Adopted MSAL 0.4.1
  • New dependency for Python 2.7: mock

New features:

  • Added credentials for authenticating users:
  • DeviceCodeCredential
  • InteractiveBrowserCredential
  • UsernamePasswordCredential
  • async versions of these credentials will be added in a future release

1.0.0b1 (2019-06-28)

Version 1.0.0b1 is the first preview of our efforts to create a user-friendly and Pythonic authentication API for Azure SDK client libraries. For more information about preview releases of other Azure SDK libraries, please visit https://aka.ms/azure-sdk-preview1-python.

This release supports service principal and managed identity authentication. See the documentation for more details. User authentication will be added in an upcoming preview release.

This release supports only global Microsoft Entra tenants, i.e. those using the https://login.microsoftonline.com authentication endpoint.
