🔐 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).
