Login System - Secure Your Server! 🔐

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

✨ Features:

  • Player Authentication:
    Requires players to register and log in before interacting with the server.

  • Auto-Kick for Unauthenticated Players:
    Prevents movement and interactions until players log in.

  • Configurable Settings:
    Customize login timeout, messages, database options, waiting area coordinates, and more via the config file.

  • Waiting Area & Position Restoration:
    When a player joins without logging in, their original position is saved and they are teleported to a configurable waiting area. Upon successful login or registration, they are returned to their original position.

  • Inventory Hiding & Blindness Effect:
    Unauthenticated players have their inventory hidden and a blindness effect applied until they log in.

  • Double Login Prevention:
    Prevents duplicate logins by disconnecting any additional connection with the same UUID.

  • Admin Commands:
    Provides admin commands to view or delete stored passwords.

🔧 How to Use:

  1. Install the Mod:
    Place the mod into your Forge server’s mods folder.

  2. Configure the Settings:
    Edit the config/loginsystem.properties file to customize your settings (login timeout, messages, database configuration, waiting area coordinates, etc.). The file includes detailed comments above each setting to help you understand their purpose.

  3. Player Commands:

    • Use /register <password> <confirmPassword> to register.
    • Use /login <password> to log in.
    • Use /changepassword <oldPassword> <newPassword> to change your password.
    • Admins can use /loadmin info <player> and /loadmin delete <player> for management.

📥 Download & Installation:

  • Mod Loader: Forge (compatible with Minecraft 1.20+)
  • Minecraft Version: 1.20+
  • No Dependancies Needed (In Latest Versions Only)
