An information processing system establishes connection between an information storage apparatus and an application installed in a terminal including a storage device for storing authentication information. The information processing system includes a setting information acquisition unit configured to acquire setting information from the information storage apparatus when the terminal receives an execution request to execute the application, the setting information indicating whether to prompt input of the authentication information. The information processing system also includes an authentication process unit configured to display a screen for inputting the authentication information on a display device of the terminal when the setting information acquired by the setting information acquisition unit calls for prompting input of the authentication information, and determine executability of the application when the authentication information that is input via the screen displayed on the display device matches the authentication information that is stored in the storage device.
