I built something like this about 5 yrs ago, applied to YC and they said nope. This is the future, password sucks. The only issue with this is there's still a password in the background and you still have to register. My solution was no signup forms, no passwords. You click one button to sign up to a site, you tap your phone to sign in. This kinda shouldn't belong with Google tho, Google, Facebook wants to use this to keep you to lock you in to their ecosystem. A 3rd party that does only this with absolutely no lock-in is ideal.
