 When you access blob or queue data using the [Azure portal](https://portal.azure.com), the portal makes requests to Azure Storage under the covers. A request to Azure Storage can be authorized using either your Azure AD account or the storage account access key. The portal indicates which method you are using, and enables you to switch between the two if you have the appropriate permissions.  
 
+You can also specify how to authorize an individual blob upload operation in the Azure portal. By default the portal uses whichever method you are already using to authorize a blob upload operation, but you have the option to change this setting when you upload a blob.

 ## Permissions needed to access blob or queue data
 
 Depending on how you want to authorize access to blob or queue data in the Azure portal, you'll need specific permissions. In most cases, these permissions are provided via role-based access control (RBAC). For more information about RBAC, see [What is role-based access control (RBAC)?](../../role-based-access-control/overview.md).
