Unlike password-based solutions that require you to remember just another PIN or password, sezame is a secure and simple multi-factor authentication solution. 
You only need the username and your fingerprint on your smartphone to log into any sezame-enabled site.

Sezame

Passwordless multi-factor authentication.
