It doesn't even ask for a password. I don't think it would be too much work to create a Persona service like 33mail.com, which provides your own domain for email and authentication. That way, you would enter "myaddress@domain.33mail.com", the site would send you there for auth, 33mail would reply that you are logged in to your account (if you were, obviously), and that'd be all.
