Disclosed are various embodiments for a computing device with an integrated authentication token. The computing device includes first circuitry having a processor and a memory and providing general-purpose computing capability. The computing device also includes second circuitry configured to generate a one-time password. The first circuitry is incapable of determining the one-time password due to a hardware, communicative, and/or electrical separation, and the first and second circuitry are in a single enclosure.
