Typically, this will be two factors and follows the pattern of authenticating with a "knowledge" factor, which is something you know, like a password, and a "possession" factor, which is something that you have. The latter is typically a key or one time password often generated by a device.

This is the same technology that was deployed for the University of Iowa Employee Self Service site.
