Fast IDentification Online
Universal Authentication Framework
FIDO UAF supports a passwordless experience. With FIDO UAF, the user carries a device with a FIDO UAF stack installed. They can then register their device to the online service by selecting a local authentication mechanism such as swiping a finger, looking at the camera, speaking into the mic, entering a PIN, etc. The FIDO UAF protocol allows the service to select which mechanisms are presented to the user.
