-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.

 Depending on how you want to authorize access to file data in the Azure portal, you need specific permissions. In most cases, you get these permissions through [Azure role-based access control (Azure RBAC)](../../role-based-access-control/overview.md).

 To access file data from the Azure portal by using your Entra account, both of the following statements must be true:
 
 - You're assigned either a built-in or custom role that provides access to file data.
-- You're assigned the Azure Resource Manager [Reader](../../role-based-access-control/built-in-roles.md#reader) role, at a minimum, scoped to the level of the storage account or higher. The **Reader** role grants the most restricted permissions, but another Azure Resource Manager role that grants access to storage account management resources is also acceptable.

You can also configure this setting for an existing storage account. This setting specifies the default authorization method only. A user can override this setting and choose to authorize data access by using the storage account key.
