You are right, things are more complicated than they seem. The
authentication dialog should be split from the authentication itself.
In case the dialog of a future authenticator may be context sensitive,
not even that will work, so it may not be a good route, so I will use a
giant or{} to squeeze all lookups into one authenticator.
