Abstract
A token apparatus is described, including (a) a controller, the controller being configured to generate an OTP in synchronization with a remote authentication server, (b) a display, the display being constructed and arranged to display the OTP, and (c) an input apparatus, the input apparatus being constructed and arranged to receive a user-input alteration code, the user-input alteration code being used to alter the OTP in a standardized manner. A method of operating a token device which displays an OTP in synchronization with a remote authentication server is described, including (a) receiving an alteration code, (b) entering the alteration code onto the token device, and (c) causing an altered OTP to be entered into an application that seeks to authenticate a user, the altered OTP having been generated from the OTP in a standardized manner based on the alteration code. An authentication system is also described.
