An authentication device has internal circuitry operable to execute specific digital processing, a digital token, an image-capturing mechanism and circuitry, and an output interface. The image-capturing mechanism captures an image providing biometric identity of a user, the internal circuitry executing a first specific digital process creates a first digital string unique to the image providing biometric identity, the internal circuitry executing a second specific digital process combines the first digital string with the digital token, creating a combined digital string, and the combined digital string is provided to the output interface.
