Pseudo-Nym, Inc. is a startup currently in stealth mode that is trying to address the problems of too many passwords. We all have too many passwords: end users, employees of small and large firms - everyone. Our goal is to replace passwords - not just complement them with an SMS text or something else - but actually replace them.
Of course, the next question is - replace them with what? That's a long story. The best place to start is here.
