Abstract: An authentication system includes: a terminal; and an information processing apparatus communicable with the terminal via a network, the authentication system being configured to perform authentication of a user who operates the information processing apparatus. The information processing apparatus includes one or more first processors configured to: accept user information for use in authentication of the user; accept terminal information for use in identification of the terminal; and identify the terminal based on the terminal information, to transmit the user information to the terminal. The terminal includes one or more second processors configured to: store a job designated by the user; receive the user information from the information processing apparatus; and perform authentication of the user based on the user information received.

Abstract: An information processing apparatus includes circuitry. The circuitry receives information related to a print job requested by a user, and determines whether the information related to the print job meets a previously determined condition. When the user requests an image forming apparatus to execute the print job and it is determined that the information related to the print job meets the previously determined condition, the circuitry executes a first authentication process for the user. When the user requests the image forming apparatus to execute the print job and it is determined that the information related to the print job fails to meet the previously determined condition, the circuitry executes a second authentication process for the user. The second authentication process is different at least partly from the first authentication process.

Abstract: An electronic device system includes a terminal device and an electronic device. The terminal device includes a memory and a sender. The memory stores user setting information about a setting of an electronic device, and the sender transmits a login request and the user setting information to the electronic device. The electronic device includes a receiver, an authentication processor, and an electronic device controller. The receiver receives the login request and the user setting information from the terminal device. The authentication processor performs a process relating to user authentication by using authentication information included in the login request. The electronic device controller controls the electronic device according to the user setting information if the user authentication performed by the authentication processor succeeds.
