Clef, two-factor authentication from future

It’s not a secret, using passwords nowadays is a pain. You have to maintain several passwords in different formats for different websites and remember answers for silly security questions. Each year complexity of your password increases and even so you can spot regular news about hackers breaking accounts of the most popular, and you would say the most secure, websites. It’s time for change. What would you say to login using your fingerprint? It’s slowly coming.

Sorry but your password must contain an uppercase letter, a number, a haiku, a gang sign, a hieroglyph and the blood of a virgin.

Clef is secure two-factor authentication with no passwords or tokens. It uses your smartphone and looks like from science fiction. Instead of entering username with password and then extra code received in SMS, you just use mobile app. The app itself is protected by fingerprint or PIN, so login to website can be matter of just one touch. And even better, if you do not login more than thousand-times a month, you can use Clef for free. Check this video clearly demonstrating how it works.

And even more fun

You can use Clef to login to many of your favourite websites. Just install browser extension Waltz.

Clef is very open to developers offering API in several programming languages – PHP, Rails, Flask and Sinatra. You can also use ready to go plugins for WordPress, Drupal, Joomla, Magento and, surprise surprise, Plesk. Integrating Clef to your own app is not difficult and it’s well documented on project’s website.

Clef is not the only U2F solution, but is definitely my favourite. You can also check Duo Security which serves same purpose slightly different way.
