Authenticates as a service principal using a client secret.

Inheritance

azure.identity._internal.client_credential_base.ClientCredentialBase

ClientSecretCredential

Constructor

ClientSecretCredential(tenant_id: str, client_id: str, client_secret: str, **kwargs: Any)

Parameters

Name	Description
tenant_id Required	str ID of the service principal's tenant. Also called its "directory" ID.
client_id Required	str The service principal's client ID
client_secret Required	str One of the service principal's client secrets

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.
cache_persistence_options	TokenCachePersistenceOptions Configuration for persistent token caching. If unspecified, the credential will cache tokens in memory.
disable_instance_discovery	bool Determines whether or not instance discovery is performed when attempting to authenticate. Setting this to true will completely disable both instance discovery and authority validation. This functionality is intended for use in scenarios where the metadata endpoint cannot be reached, such as in private clouds or Azure Stack. The process of instance discovery entails retrieving authority metadata from https://login.microsoft.com/ to validate the authority. By setting this to True, the validation of the authority is disabled. As a result, it is crucial to ensure that the configured authority host is valid and trustworthy.
additionally_allowed_tenants	List[str] Specifies tenants in addition to the specified "tenant_id" for which the credential may acquire tokens. Add the wildcard value "*" to allow the credential to acquire tokens for any tenant the application can access.

Examples

Create a ClientSecretCredential.

   from azure.identity import ClientSecretCredential

   credential = ClientSecretCredential(
       tenant_id="<tenant_id>",
       client_id="<client_id>",
       client_secret="<client_secret>",
   )

Methods
