How to change host id? It is dangerous to share your host id now because there is no protection from griefing. Like bans or whitelist...

This ID is supposed to be tied to your PC so I'm not sure it's possible to change it. Creating a new user in Windows and running the game from there might solve it, but I haven't tested it.
The game is still in the early alpha phase so it's lacking admin features like kick/ban right now. I recommend only playing with people you know.
