⚠️version 1.3.0 is incompatible with 1.2.1⚠️
A minimalist, high-performance authentication solution for Minecraft.
LunAuth is a lightweight security mod developed by O.S. TEAM. It is designed specifically for servers and helps protect them from unauthorized access and theft of personal data in offline mode.
Our philosophy is transparency and minimalism. This mod provides essential protection without unnecessary bloat, making it perfect for both small private servers and larger communities managed by technical teams.
✨ Key Features:
Simple Authentication: Standard /register and /login commands for player security.
Anti-Brute Force: Automatically kicks players after 3 failed login attempts to prevent password guessing.
Session Management: A configurable login timeout (60 seconds by default) ensures that unauthenticated players don't occupy server slots.
Player Lockdown: Frozen movement, blindness effect, and blocked interactions until the player is logged in.
Transparent Data: User credentials are stored in a clear JSON format within the config/LunAuth/ directory for easy administration.
Developer Friendly: Built by developers who value clean code and open-source principles.
🛠️ Installation & Config:
Install the mod on your NeoForge server.
Launch the server to generate the configuration file.
Edit config/LunAuth/settings.toml to customize messages, timeouts, and security limits.
Developed with a focus on performance on modern hardware, including AMD Ryzen systems. Part of the O.S. TEAM open-source initiative.
