Abstract
Multi-server passcode verification is provided for one-time authentication tokens with auxiliary channel compatibility. An exemplary method comprises receiving an authentication passcode generated by a token associated with a user; and processing the received authentication passcode using at least a first authentication server and a second authentication server, wherein the received authentication passcode is based on at least one protocode and embedded auxiliary information and wherein at least one of the first authentication server, the second authentication server and a relying party extract the embedded auxiliary information from the received authentication passcode. The disclosed method can extend an existing multi-server verification process to provide the processing of the received authentication passcode based on the embedded auxiliary information.
