HTTP Authentication can be supported. If set it will be used for both the backup and the restore operations. The authentication credentials and realm are stored in the phone's programmable, non-volatile memory, which is not overwritten when new firmware is downloaded.

Both the authentication credentials and realm have a default value of null. If the HTTP server requires authentication, the user is prompted to enter new credentials using the phone. If the authentication is successful, the values used are stored and used for subsequent backup and restore operations.
