U2F device


U2F device is a FIDO Authenticator that supports the Universal Second Factor FIDO protocol

U2F device interface types#

At the moment (2017-04-02) three interface types are specified in FIDO U2F. Unlocking is a test of user physical presence and requires a token-specific gesture, such as pushing a button on a USB device, tapping a U2F device to an NFC-enabled device such as a mobile phone or tablet, or pressing a button on a BLE-enabled token or fob.

The user can use the same FIDO U2F device on all online services that support the U2F device protocol.
