Release History

1.4.0b4 (Unreleased)

  • 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)
  • 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 Azure Active Directory'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:

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 Azure Active Directory tenants, i.e. those using the https://login.microsoftonline.com authentication endpoint.
