 # Authenticate modes for capturing events to destinations in Azure Event Hubs
 Azure Event Hubs allows you to select different authentication modes when capturing events to a destination such as [Azure Blob storage](https://azure.microsoft.com/services/storage/blobs/) or [Azure Data Lake Storage Gen 1 or Gen 2](https://azure.microsoft.com/services/data-lake-store/) account of your choice. The authentication mode determines how the capture agent running in Event Hubs authenticate with the capture destination. 
 
-## SAS based authentication 
-The default authentication method is to use Shared Access Signature(SAS) to access the capture destination from Event Hubs service. 
+## Use managed identity

-With this approach, you can capture data to destinations resources that are in the **same subscription** only.

-## Use managed identity 
-With [managed identity](../active-directory/managed-identities-azure-resources/overview.md), users can seamlessly capture data to a preferred destination by using Microsoft Entra ID based authentication and authorization. 
+[Managed identity](../active-directory/managed-identities-azure-resources/overview.md) is the preferred way to seamlessly access the capture destination from your Event Hub, using Microsoft Entra ID based authentication and authorization.
