Is it impossible for TAB to appear in a password?  If it is, the TAB
is okay, and my only reservation about that is that TAB is not
generally interpreted in my mental model of "advanced" input  patterns
as something that hides/shows stuff.  TAB is more about completion and
similar functionality.  But that's me.

Let's hear opinions from others.
