SAuth

🛡️ Server Registration Mod

Server Registration Mod adds a simple but powerful player authentication system for Minecraft servers running Forge 1.20.1. It requires every player to register and log in before they can move, break blocks, or interact with the world — perfect for small servers without online mode or external plugins.

✨ Features

🔐 Player registration and login system Players must use /register <password> and /login <password> to access the game.

⚙️ Operator command Admins can change any player’s password using /changepw <nickname> <newpassword>.

🚫 Action blocking before login Unauthenticated players cannot move, break, attack, or interact until they log in.

💬 Chat allowed before login Players can still talk in chat, so you can help them if they forget their password.

💾 Secure SHA-256 password storage Passwords are stored safely in config/serverreg/users.json.

🎨 Custom join message Players see a bright, clear message reminding them to log in or register when they join.

🧱 Perfect for:

Offline-mode or LAN servers

Private roleplay servers

Small friend groups who want basic account protection

⚠️ Notes

Works server-side only (no need to install it on the client).

Does not require a database — all data is stored locally as JSON.

Compatible with any Forge 1.20.1 modpack.
