By default, a container and any blobs within it may be accessed only by the owner of the storage account. If you want to give anonymous users read permissions to a container and its blobs, you can set the access control list (ACL) for the container to allow public access. Anonymous users can read blobs within a publicly accessible container without authenticating the request.

Note
If your service requires that you exercise more granular control over blob resources, or if you wish to provide permissions for operations other than read operations, you can use a Shared Access Signature to make a resource accessible to users. See Creating a Shared Access Signature for more information.

The following table shows which operations may be called by anonymous users when a container's ACL is set to allow public access.
