Abstract
A processorless hardware token provides a one-time password for user authentication. The processorless hardware token contains a non-volatile memory upon which is stored a pre-produced sequence of one-time passwords. The processorless hardware token uses limited circuitry on a circuit board to read from the non-volatile memory and display a one-time password associated with a current interval. The displayed one-time password is then used for authentication by an authentication server that compares the one-time password displayed on the processorless hardware token with a one-time password retrieved from a copy of the pre-produced sequence of one-time passwords stored on the Authentication Server.
