Abstract:
1. A method, implemented by a computer-implemented authentication system, for authenticating a user attempting to access a target component of a computer system from a first user system, the first user system being connectable to a first communications network, the method comprising: receiving, by at least one computing device, user authentication information entered by the user via a first user-interface of the first user system; obtaining, by the at least one computing device, via the first communications network a session identifier and at least one item of contextual information identifying the first user system or a property of the first communications network; verifying, by the at least one computing device, the user authentication information, and responsive to successful verification of the user authentication information, sending a message from the computer-implemented authentication system via a second communications network to a second user system, the message comprising receiving, by the at least one computing device, via the first user system and the first communications network a passcode entered by the user into the first user system; verifying, by the at least one computing device, the entered passcode against the real-time session-specific one-time passcode and/or the session identifier; and responsive to a successful verification of the entered passcode, granting to the first user system access to the target component.
