    That's very clever. 
    
    Not really a proper review comment, I just wanted to mention it :)

    We probably don't want this.

    This isn't used

    AFAIK this is now unused?

    Given this is in a file under "themes" we probably want to put the Authenticator object in the C++ and expose that to the QML then connect succeeded signal there.  Otherwise we are trusting that the QML is doing the right thing.
    
    Without this one could replace a local user's lock screen theme file and add a backdoor.

    Previous behaviour (and general convention) is normally for the password to stay but to be selected when the password is wrong.
    
    (no idea why, everyone always ends up retyping it)
