Fedora's invisible passwords and visible squabbles

I agree, similar issues turn up for me in switching between US/Dutch and German keybord mappings; and some keyboards have an easy to trigger caps lock without indication too. Guests with weird keyboards/me visiting friends, with no WPS, but needing wifi come to mind as well.

Not showing anything but having an option to verify what was typed is quite useful. If you remain in a save environment while that option is available, that is; of others can acccess the option, it is a potential problem, though not so much in that wifi router case where it is a shared secret. Remaining at the keyboard until you typed the password seems like a decent workaround in anycase.
