Communication device and non-transitory computer-readable recording medium storing computer-readable instructions for communication device

A non-transitory computer-readable recording medium storing computer-readable instructions for a communication device,

• wherein the computer-readable instructions, when executed by a processor of the communication device, cause the communication device to:
• receive a specific signal from a first external device via a first wireless interface of the communication device;
• after the specific signal is received from the first external device, cause a display unit of the communication device to display a first instruction screen for receiving an instruction that a target process which includes sending of a public key is to be executed;
• in a case where it is instructed that the target process is to be executed in a situation where the first instruction screen is displayed, send the public key to the first external device via the first wireless interface,
• wherein in a case where it is not instructed that the target process is to be executed in the situation where the first instruction screen is displayed, the public key is not sent;
• after the public key has been sent to the first external device, receive an authentication request, in which the public key is used, from the first external device via a second wireless interface of the communication device;
• in a case where the authentication request is received from the first external device, send an authentication response to the first external device via the second wireless interface;
• after the authentication response has been sent to the first external device, receive connection information from the first external device via the second wireless interface, the connection information being for establishing a wireless connection between the communication device and a second external device via the second wireless interface;
• and
• in a case where the connection information is received from the first external device, establish, by using the connection information, the wireless connection between the communication device and the second external device via the second wireless interface.
