U2F is an open authentication standard that enables keychain devices, mobile phones, and other devices to securely access any number of web-based services — instantly and with no drivers or client software needed. U2F was created by Google and Yubico, with contribution from NXP, and is today hosted by the open-authentication industry consortium, FIDO Alliance. For more information about YubiKey and U2F, see U2F – FIDO Universal 2nd Factor.
