  Azure Machine Learning compute clusters also support [managed identities](../articles/active-directory/managed-identities-azure-resources/overview.md) to authenticate access to Azure resources without including credentials in your code. There are two types of managed identities:
 
 * A **system-assigned managed identity** is enabled directly on the Azure Machine Learning compute cluster. The life cycle of a system-assigned identity is directly tied to the compute cluster. If the compute cluster is deleted, Azure automatically cleans up the credentials and the identity in Azure AD.
-* A **user-assigned managed identity** is a standalone Azure resource provided through Azure Managed Identity service. You can assign a user-assigned managed identity to multiple resources, and it persists for as long as you want.

This managed identity needs to be created beforehand and then passed as the identity_id as a required parameter.
