About this Mod
[ LunAuth ] 🛡️
⚠️version 1.3.0 is incompatible with 1.2.1⚠️
A minimalist, high-performance authentication solution for NeoForge.
LunAuth is a lightweight security mod developed by O.S. TEAM. It is designed specifically for NeoForge 1.21.1 to protect your server from unauthorized access and identity theft 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-blocked: 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.

LunAuth server crashes on startup – what to do?
Most common cause: wrong neoforge 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 (1.21.1). You can switch loaders with one click in the panel.
Is LunAuth compatible with neoforge?
LunAuth officially supports neoforge for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with LunAuth – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if LunAuth 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.
