Clef is two-factor from the future.

As we move more of our personal information into the cloud, we need security we can actually use.

Clef uses the mass adoption of smartphones to make an identity platform for the modern web, creating a totally new approach to logging in online. We've built two-factor authentication that lets sites recognize their users with a wave of their phones. Clef puts secure cryptography in the hands of every user — no weak passwords, frustrating tokens, or clunky dongles.
