According to one embodiment, a control module determines whether a second authentication key is present in a authentication key storage device when an information processing apparatus is powered on. The control module displays an identification code input screen for inputting an identification code if the second authentication key is not present, causes a storage device to execute an identification code authentication process of determining whether the identification code which is input to the identification code input screen agrees with the first identification code, and generates a third authentication key and stores the third authentication key in the authentication key storage device if the identification code authentication process is successfully carried out.
