SimpleAuth Mod

Now supports Forge and Fabric!

Do you have a server that you want to protect from unwanted visitors without using whitelist? Or need an extra form of authentication for players?

This mod will come in handy then - it denies moving, destroying blocks etc. for players that aren't registered / logged in. It's possible to set a global password as well, check wiki for more details.

Make sure to download the right version, depending on your server being Fabric or Forge one!

(Fabric version only)
