Abstract
An authentication system includes an in-vehicle device that generates an authentication key, and displays on a display unit, a two-dimensional code including the generated authentication key and a URL indicating a predetermined WEB page on a network. A portable terminal device acquires the authentication key and the URL from the two-dimensional code by reading the two-dimensional code via an imaging unit, downloads a communication program for communicating with the in-vehicle device from the WEB page indicated by the URL, and transmits the authentication key to the in-vehicle device by causing the downloaded communication program to operate.
