About this Mod
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
Datapack installation:
- Locate the datapack folder for the specific world
- Drag the Login.zip file into the datapack folder

Login server crashes on startup – what to do?
Most common cause: wrong datapack version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.
Is Login compatible with datapack and fabric and forge and neoforge and quilt?
Login officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 26.1.2, 26.1.1, 26.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Login – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Login consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
