!!! Overview[1][2]
[{$pagename}] ([U2F]) [protocol] is a [FIDO protocol] is an open [authentication] standard that strengthens and simplifies [Multi-Factor Authentication] using specialized [USB] or [NFC] devices based on similar security technology found in [Smart Cards].
[{$pagename}] initially developed by [Google] and [Yubico], with contribution from [NXP Semiconductors], the standard is now hosted by the [FIDO] Alliance.
[{$pagename}] allows online services to augment the security of their existing [password] infrastructure by requiring a [Hard token] using a [FIDO Authenticator].
The [authenticator] provides an additional [Authentication Factor] to augment user login.
!! [{$pagename}] [Authentication] process
In a [U2F] deployment the [Authentication] process is similar to
* the user logs in to an [Service Provider] as usual (ie using [Password Authentication])
* the [user] is presented with a Challenge [user] "unlocks" the [U2F device] by using a [Personal Entity] [presence].
* [U2F device] proves possession of the [Private Key] to the [Service Provider] by signing the challenge.
!! [Universal Second Factor Challenges]
There are some [Universal Second Factor Challenges] that need to be considered.
