Abstract
An authentication device comprises a processor having a reset input, a trigger source coupled to the reset input of the processor, and interface circuitry for outputting codes generated by the processor. The trigger source may comprise, for example, a trigger button having an associated switch that when actuated supplies a reset to the reset input. The processor is configured to analyze a given reset applied to the reset input to determine if the reset is an inadvertent reset or a reset generated by the trigger source. The processor generates a code responsive to the reset if the reset is determined to be a reset generated by the trigger source. The code may be supplied to a host device which communicates the code to an authentication server for authentication.
