Temporary password?! Isn't the whole point of multi-factor authentication that if you do need to jump through extra hoops, they're hoops that you have already designed yourself? These days probably something more specialized than the once-popular "mother's maiden name" ... which may well be your own current name.
This release is built on top of Twitter via SMS, so we need to be able to send a text to your phone before you can enroll in login verification (which may not work with some cell phone providers).
And, er, not to belabor the obvious, but it will definitely not work on any non-cellular telephones.
