Function executing device, non-transitory computer-readable recording medium storing computer-readable instructions for function executing device, and method for controlling function executing device

A non-transitory computer-readable recording medium storing computer-readable instructions for a function executing device configured to execute a scan function, wherein the function executing device comprises:

• a scan engine;
• and
• a processor, wherein
• the computer-readable instructions, when executed by the processor, cause the function executing device to:
• receive a related instruction related to execution of a scan from an external device;
• in a case where the related instruction is received from the external device via a first communication path for executing an encrypted communication, send an authentication information request to the external device;
• in response to the authentication information request being sent to the external device, receive specific authentication information from the external device via the first communication path;
• and
• in a case where a user authentication according to the specific authentication information succeeds, execute a first scan process,
• wherein the first scan process comprises:
• causing the scan engine to scan a document;
• and
• sending scan data to the external device via the first communication path,
• and in a case where the user authentication according to the specific authentication information fails, the first scan process is not executed,
• wherein in a case where the related instruction is received from the external device via a second communication path for executing an unencrypted communication, the authentication information request is not sent to the external device.

A method for controlling a function executing device configured to execute a scan function and comprising a scan engine,

• the method comprising:
• receiving a related instruction related to execution of a scan from an external device;
• in a case where the related instruction is received from the external device via a first communication path for executing an encrypted communication, sending an authentication information request to the external device;
• in response to the authentication information request being sent to the external device, receiving specific authentication information from the external device via the first communication path;
• and
• in a case where a user authentication according to the specific authentication information succeeds, executing a first scan process,
• wherein the first scan process comprises:
• causing the scan engine to scan a document;
• and
• sending scan data to the external device via the first communication path, and
• in a case where the user authentication according to the specific authentication information fails, the first scan process is not executed,
• wherein in a case where the related instruction is received from the external device via a second communication path for executing an unencrypted communication, the authentication information request is not sent to the external device.
