Non-transitory computer-readable medium storing computer-readable instructions for terminal device and terminal device

A non-transitory computer-readable medium storing computer-readable instructions for a terminal device, wherein the computer-readable instructions, when executed by a processor of the terminal device, cause the terminal device to:

• obtain from a communication device a public key of the communication device and target identification information identifying the communication device, the target identification information being one of first identification information identifying the communication device and second identification information identifying the communication device, the first identification information being for the communication device to establish a wireless connection with an external device that is different from the terminal device, the second identification information being for the communication device to establish a wireless connection with the terminal device, the second identification information being different from the first identification information;
• after the public key and the target identification information have been obtained from the communication device, send an authentication request in which the public key is used, to the communication device via a wireless interface of the terminal device;
• after the authentication request has been sent to the communication device, receive an authentication response, which is a response to the authentication request, from the communication device via the wireless interface;
• in a case where the target identification information is the first identification information and the authentication response is received from the communication device, send first connection information to the communication device via the wireless interface, the first connection information being for the communication device to establish the wireless connection with the external device;
• in a case where the target identification information is the second identification information and the authentication response is received from the communication device, send second connection information different from the first connection information to the communication device via the wireless interface, the second connection information being for the communication device to establish the wireless connection with the terminal device;
• and
• after the second connection information has been sent to the communication device, establish the wireless connection with the communication device via the wireless interface by using the second connection information.
