What is a key fob?

A key fob is a small, programmable device that provides access to a physical object. Also known as ahardware token, a key fob provides on-device, one-factor authentication to facilitate access to a system or device, such as a car, computer system, restricted area or room, mobile device, network service or other kind of keyless entry system.

With a key fob, the user does not have to unlock the device with a real key as with manual locks. In addition to providing remote-enabled access, the key fob is more convenient and more secure.

Key fobs are among a class of physical security tokens that includes smart cards, proximity cards and biometric keyless entry fobs.
