 When you access file data by using the [Azure portal](https://portal.azure.com?azure-portal=true), the portal makes requests to the Azure Files service behind the scenes. You can authorize these requests by using either your Microsoft Entra account (preferred) or the storage account access key (less secure).
 
-The portal shows which method you're using and enables you to switch between the two methods if you have the appropriate permissions. By default, the portal uses whichever method you're already using to authorize all file shares, but you can change this setting for individual file share operations.

-> When you lock a storage account by using a Resource Manager **ReadOnly** lock, you can't perform the [List Keys](/rest/api/storagerp/storageaccounts/listkeys) operation for that storage account. **List Keys** is a POST operation, and all POST operations are prevented when a **ReadOnly** lock is configured for the account. For this reason, when you lock the account by using a **ReadOnly** lock, you must use Entra credentials to access file data in the portal.
