Abstract
A distributed passcode verification system includes devices that each have a hardware secret and that are each able to perform a limited number of verifications using their hardware secrets. Passcode verifiers receive passcode information from a passcode information manager. The passcode information provides information usable, with a hardware secret, to verify passcodes provided to a verifier.
