SharedTokenCacheCredential

Constructor

SharedTokenCacheCredential(username: str | None = None, **kwargs: Any)

Name	Description
username	str Username (typically an email address) of the user to authenticate as. This is used when the local cache contains tokens for multiple identities. Default value: None

Keyword-Only Parameters

Name	Description
authority	str Authority of a Microsoft Entra endpoint, for example 'login.microsoftonline.com', the authority for Azure Public Cloud (which is the default). AzureAuthorityHosts defines authorities for other clouds.
tenant_id	str a Microsoft Entra tenant ID. Used to select an account when the cache contains tokens for multiple identities.
authentication_record	AuthenticationRecord an authentication record returned by a user credential such as DeviceCodeCredential or InteractiveBrowserCredential
cache_persistence_options	TokenCachePersistenceOptions configuration for persistent token caching. If not provided, the credential will use the persistent cache shared by Microsoft development applications

Methods

close	Close the credential's transport session.
get_token	Get an access token for scopes from the shared cache. If no access token is cached, attempt to acquire one using a cached refresh token. This method is called automatically by Azure SDK clients.
get_token_info	Request an access token for scopes. If no access token is cached, attempt to acquire one using a cached refresh token. This is an alternative to get_token to enable certain scenarios that require additional properties on the token. This method is called automatically by Azure SDK clients.
supported	Whether the shared token cache is supported on the current platform.
