METHOD, INFORMATION PROCESSING APPARATUS, AND NON-TRANSITORY COMPUTER READABLE MEDIUM

An information processing apparatus acquires, via an in-vehicle communication apparatus of a vehicle, user information on a user linked to the vehicle. Next, the information processing apparatus identifies a terminal apparatus linked to the user. When the vehicle supports digital keys and the user has a digital key contract, the information processing apparatus displays, on a screen, first information to perform both authentication of the user and registration of a digital key to the vehicle using the identified terminal apparatus. Otherwise, the information processing apparatus displays, on the screen, second information to perform authentication of the user using the identified terminal apparatus.
