摘要： A user friendly two factor authentication method and system for a user is disclosed. In an embodiment the system includes a user device, an authentication server, a network interconnecting the user device and authentication server and software on the user device and authentication server that cooperates to first register the user by storing first key share K1 of an authentication key K on the user device and storing a second key share K2 of K blinded by a user chosen password on the authentication server, and then authenticate the user by implementing a protocol where the user's knowledge of the password and the possession of the user device is used to derive the key K for authentication. Thus, the two factors are checked in one integrated protocol, thereby requiring no additional work or change in user behavior.
