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.
