 # Authorize access to blobs using Azure Active Directory
 
-Azure Storage supports using Azure Active Directory (Azure AD) to authorize requests to blob data. With Azure AD, you can use Azure role-based access control (Azure RBAC) to grant permissions to a security principal, which may be a user, group, or application service principal. The security principal is authenticated by Azure AD to return an OAuth 2.0 token. The token can then be used to authorize a request against the Blob service.

The security principal is authenticated by Azure AD to return an OAuth 2.0 token. The token can then be used to authorize a request against the Blob service. Note that this is only supported for API versions 2017-11-09 and later. For more information, see [Versioning for the Azure Storage services](/rest/api/storageservices/versioning-for-the-azure-storage-services#specifying-service-versions-in-requests).
 
 Authorizing requests against Azure Storage with Azure AD provides superior security and ease of use over Shared Key authorization. Microsoft recommends using Azure AD authorization with your blob applications when possible to assure access with minimum required privileges.
