A login processing unit performs a login process of a user. An assignment processing unit assigns an inputting device connected to an information processing apparatus to a user. An assignment processing unit controls an assignment process of the inputting device in response to the number of users who are in a login state and executes an assignment process which is different between a case in which the number of users in a login state is one and another case in which the number of users in a login state is two or more. The assignment processing unit assigns, when the number of users in a login state is one, the inputting device connected to the information processing apparatus to the one user.
