Abstract
Methods and apparatus are provided for signing data transactions using one-time authentication passcodes. User authentication passcodes are generated by generating a time-based user authentication passcode based on a forward-secure pseudorandom number, wherein the generated time-based user authentication passcode is used for authentication of the user; and generating an event-based user authentication passcode based on a forward-secure pseudorandom number, wherein the generated event-based user authentication passcode is used to sign one or more data transactions. The generation of an event-based user authentication passcode can be performed on-demand. The generation of the event-based user authentication passcode can optionally be performed substantially simultaneously with the generation of the time-based user authentication passcode.
