The PC 1 waits for reception of a communication connection permission instruction at the operation unit 14 (S34), and when a communication connection non-permission instruction is received (S34: NO), the CPU 11 ends the process. When an instruction to permit communication connection is received by the operation unit 14 (S34: YES), the CPU 11 starts communication connection using the connection information (S35). In S35, for example, the CPU 11 uses the communication unit 17 to access the communication device specified by the IP address included in the connection information via the communication network 5. Next, the CPU 11 waits for a password request from the communication device of the communication connection destination (S36). The password request is received by the communication unit 17. If the password request is not received by the communication unit 17 (S36: NO), the CPU 11 continues to wait for the password request. When the password request is received by the communication unit 17 (S36: YES), the CPU 11 causes the communication unit 17 to transmit the password included in the connection information unique to the communication connection destination communication device to the communication connection destination communication device. (S37), the process ends.
