Login System v2.0

Login System – Secure Your Server!

Login System is a simple yet powerful mod that adds a registration and login system for offline-mode Minecraft servers. It ensures players must authenticate before playing, preventing impersonation and unauthorized access.

Features

Player Authentication 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.

Double Login Prevention Blocks duplicate connections with the same UUID (disconnects the second session).

Admin Commands
