A system, apparatus, method, and machine readable medium are described for authenticating a client to a device. For example, one embodiment of a method comprises: registering an authenticator of a client with a relying party, the registration allowing a user of the client to remotely authenticate the user to the relying party over a network; generating a first authentication structure using at least a first authentication key associated with the authenticator and a signature generated with a first verification key; caching the first authentication structure on the client; providing a second verification key corresponding to the first verification key to a transaction device; performing an authentication transaction between the client and the transaction device in which the client generates a second authentication structure using a second authentication key associated with the first authentication key, the transaction device uses the second verification key to validate the signature on the first authentication structure and uses the first authentication key to validate the second authentication structure. |
