Abstract
A method and apparatus provides user authentication by communicating primary authentication information, such as user identification data and/or password data to an authentication unit via a primary channel such as over the Internet. An authentication code is generated by the authentication unit on a per session basis and is sent to a destination unit via a first secondary channel during the session. The destination unit then retransmits the authentication code, on a second secondary channel, to the first unit in a way that is transparent to a user of the first unit. The first device then send the received re-transmitted authentication code back to the authentication unit via the primary channel during the session.
