Universal 2nd Factor (U2F) is an open authentication standard that strengthens and simplifies two-factor authentication (2FA) using specialized USB based security technology found in smart cards.

FIDO U2F devices are used to create the key pairs and “store” all the private keys. Only the public keys are stored by the website.

The U2F device generates a digital signature with the private key within the secure element and returns the digital signature and an incrementing counter value.

Strong Security: Strong two-factor authentication using public key crypto that protects against phishing, session hijacking, man-in-the-middle, and malware attacks.

Note As of now FIDO supports google chrome and mozila. In mozila firebox some configuration has to be added.
