This datapack enforces security on your server by forcing users to login with a password. When a user first joins your server they will be asked to provide a numerical password by typing:

/trigger login set <password>

When the player joins your server for the second time they will be asked for the same password they once provided.

Until the player has provided a password they will be put into spectator mode and locked at their last position to prevent the player from causing any harm.

Please take a backup of your world/server in the case that this mod conflicts with anything you have installed and wipes your player-data. Please also take regular backups if you are using this datapack, as it isn't as secure as a mod

Datapack installation:

  1. Locate the datapack folder for the specific world
  2. Drag the Login.zip file into the datapack folder
  3. Enable the datapack with /datapack enable "file/Login.zip"

Mod instalation:

  1. Follow the instructions on how to install your prefered modloader (be it Forge, Fabric, NeoForge or Quilt)
  2. Drag the downloaded .jar file into (on windows) %appdata%.minecraft\mods
  3. Launch the world and start playing
