The local unlock is accomplished by a user–friendly and secure action such as swiping a finger, entering a PIN, speaking into a microphone, inserting a second–factor device or pressing a button. The client’s private keys can be used only after they are unlocked locally on the device by the user. During registration with an online service, the user’s client device creates a new key pair. Authentication is done by the client device proving possession of the private key to the service by signing a challenge. The FIDO protocols use standard public key cryptography techniques to provide stronger authentication. FIDO Conformance Tools v1.7.10 FIDO2 Server - MDS3 Metadata Service Tests are failing. What is your implementation class Security Key / FIDO2 / U2F authenticators. It retains the private key and registers the public key with the online service. U2F 1.1 U2F 1.2 NOTE: UAF 1.0 certification have been officially sunset.
