What is a Key Fob?

A fob, commonly called a key fob, is a small security hardware device with built-in authentication used to control and secure access to mobile devices, computer systems, network services and data. The key fob displays a randomly generated access code, which changes periodically usually every 30 to 60 seconds. Users will first authenticate themselves on the key fob with a personal identification number (PIN), followed by the current code displayed on the device.
