A second information processing system to communicate with a first information processing system includes an acquisition unit, an acceptance unit, a confirmation unit, and a setting unit. The acquisition unit acquires authentication information from the first information processing system and from a memory of the second information processing system. The acceptance unit accepts correspondence information indicating correspondence between first authentication information and second authentication information. The confirmation unit confirms, as a condition, whether the acquired authentication information in the first information processing system is identical to the accepted first authentication information and confirms, as a condition, whether the acquired authentication information in the second information processing system is identical to the accepted second authentication information. The setting unit does not set the correspondence information as single sign-on setting information if a condition is not satisfied and sets the correspondence information as single sign-on setting information if both conditions are satisfied.
