PROBLEM TO BE SOLVED: To simplify a user's input operation for logging in to electronic devices by providing the user with a common interface for logins to a plurality of electronic devices. SOLUTION: A main device 2 stores first authentication information for user authentication with a client device 3 and second authentication information for user authentication between units 1 and the client device 3, sends a login request screen to the client device 3 after user authentication, and when any unit 1 is selected on the login request screen, sends a login request to which the second authentication information associated with the unit 1 is added. The unit 1 acquires the second authentication information associated therewith, and executes user authentication based on the second authentication information added to the login request and the acquired second authentication information.
