How about using an interaction icon with the KeyPress response ( thats what
I do ) ? I have 3 KeyPress branches, one for Enter, one for BackSpace/Delete
and one for any other key (?). You can then build the password by
concatenating the keypresses until Enter is hit. If you want to display
something you can concatenate a second string with any character you like
and display that ( I use asterisks ). This is a bit more cumbersome than
a simple text interaction but it seems to work o.k.

(-: Cheers :-)
