    authPrompt: Wiggle error messages coming from the Fingerprint service
    
    When error messages are coming from the fingerprint service they are actual
    failures due to an user input in some device, in so in such case we
    can highlight this by using a wiggle effect.
    
    This mimics what has been done in gnome-control-center fingerprint panel
    and part of [1].
