Can a single factorio account play two+ players on multi?

Can a single factorio account play as two or more players on multiplayer server? I'd like to debug some of my mods in multiplayer-mode, but am not sure how.

You can play over LAN or direct connect without signing into a factorio account

Thanks, I'll try to figure that out.

You'll need to go into the config file and change the port of one copy if you are testing on the same system
