All Ways to Enable Telnet on Windows 11 Computer

Telnet is a built-in remote access utility that you can use to troubleshoot firewalls and networks. Although it is still part of Windows, system administrators now prefer the more secure SSH protocol for accessing computers over unsecured networks.

The main disadvantage of Telnet is that it is insecure and vulnerable to Man-in-the-Middle attacks. If not in specific situations, switch to more secure network protocols like SSH and Mosh with better passwords and public key authentication.
