Players must /register and /login before interacting with the server.

Auto-Kick & Restrictions
Unauthenticated players cannot move or interact until they log in.

Configurable Settings
Fully customizable via config/loginsystem.properties (timeout, messages, database options, waiting area coordinates, etc.).

Waiting Area & Position Restore

Saves the player’s original position when joining.

Teleports them to a configurable waiting area.

Restores their position after successful login/registration.

Inventory Hiding & Blindness
Unauthenticated players have their inventory hidden and a blindness effect applied.

Frequently Asked Questions

Login System server crashes on startup – what to do?

Most common cause: wrong fabric 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 System compatible with fabric and forge and neoforge?

Login System officially supports fabric, forge, neoforge 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 System – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Login System 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.
