 ## Huge thanks
 
-Thanks to [@comed-ian](https://github.com/comed-ian) for creating a working proof of concept python script that successfully authenticated using the new authentication method in RouterOS 4.43+, and [@kmeaw](https://github.com/kmeaw) for porting the code to C, and implementing it in mactelnet and mactelnetd.
