Log in to StackOverflow with your smartphone

This is a game changer, or at least a huge step in the right direction. I shouldn't have to wait for individual websites to make systems like this, third parties like Clef should handle it for everyone.

We totally agree. Having every site try to re-implement and keep up with security best practices is a waste of time, money, and makes it hard to trust anyone online.

Current login systems are as fragmented as anything else I can think of on the web

Congratulations guys! I added the clef plugin to my wordpress blog as soon as I found out about it - it's working great.

Stackoverflow was one of the sites I wanted to see this working on!

This is very awesome, congrats Jesse and team!

i don't know. why should i trust clef?

the google two-factor authentication can be run on your own server. can clef be run w/o clef? i don't think so.
