![]() The local unlock is accomplished by a user inserting a uTrust FIDO2 Security Key or pressing the NFC button on the security key. ![]() The client’s private keys can be used only after they are unlocked locally on the device by the user. Authentication is done by the client device proving possession of the private key to the service by signing a challenge. It retains the private key and registers the public key with the online service.

FIDO2 enables users to leverage common devices to easily authenticate to online services in both mobile and desktop environments. FIDO2 is the term for FIDO Alliance’s newest set of specifications. FIDO U2F is an open standard that provides added security and simplifies Universal 2-Factor authentication. This is accomplished by using standard public-key cryptography to provide strong authentication and leave zero data at rest. Based on free, open standards from the FIDO Alliance, Fast IDentity Online (FIDO) authentication enables password-only logins to be replaced with secure, fast login experiences across websites and apps.
