I'd like a typical GUI browser to let me right-click a password field and use a "show secret text" option. But it should never be the default, at least not for people like me who present on laptops too infrequently to form defensive habits around what my colleagues are about to see.

Why oh why can't we just carry around certs on USB fobs? Isn't it the future yet?

I wholeheartedly agree with this solution with the additional possibility that you cookie the user's choice. Solutions like firefox plugins are fine for you and me, but not for the remedial computer users who mistype their passwords in the first place. On my sites, the vast majority of customer service calls/emails are people who can't log in, simply because they can't figure out how to type in their passwords correctly (we don't even have a attempts limit - they can try as many times as they like).

I've talked about this on the other duplicate post but honestly how often do you want that? You can always just open a text editor type it in that (or the address bar, whatever) and then copy and paste it.
