Azure Synapse workspace managed identity

In this article, you'll learn about managed identity in Azure Synapse workspace.

Managed identities

Managed identity for Azure resources is a feature of Azure Active Directory. The feature provides Azure services with an automatically managed identity in Azure AD. You can use the Managed Identity capability to authenticate to any service that support Azure AD authentication.

Managed identities for Azure resources are the new name for the service formerly known as Managed Service Identity (MSI). See Managed Identities to learn more.

Azure Synapse workspace managed identity

A system-assigned managed identity is created for your Azure Synapse workspace when you create the workspace.


This workspace managed identity will be referred to as managed identity through the rest of this document.

Azure Synapse uses the managed identity to integrate pipelines. The managed identity lifecycle is directly tied to the Azure Synapse workspace. If you delete the Azure Synapse workspace, then the managed identity is also cleaned up.

The workspace managed identity needs permissions to perform operations in the pipelines. You can use the object ID or your Azure Synapse workspace name to find the managed identity when granting permissions.

Retrieve managed identity in Azure portal

You can retrieve the managed identity in Azure portal. Open your Azure Synapse workspace in Azure portal and select Overview from the left navigation. The managed identity's object ID is displayed to in the main screen.
