Description

NefAuth - Simple Login & Register for NeoForge

A lightweight, secure, and server-only authentication mod designed for NeoForge 1.21.1.

Perfect for large modpacks like All the Mods (ATM) running in offline mode (online-mode=false) to prevent unauthorized access and account theft.

Features

  • Server-Only: Players do not need to install this mod on their clients. Just drop it into the server's mods folder.
  • Secure Hashing: Password protection using secure hashing algorithms (no plain-text passwords stored).
  • Session Management: Prevents players from moving, chatting, or executing commands before logging in.
  • NeoForge Native: Built specifically for NeoForge 1.21.1, ensuring maximum compatibility without the need for buggy hybrid server jars (like Arclight/Mohist).

Commands

  • /register <password> <confirmPassword> - Register a new account.
  • /login <password> - Log into your account.
  • /changepassword <oldPassword> <newPassword> - Change your current password.

Installation & Setup

  1. Download the .jar file for NeoForge 1.21.1.
  2. Place it into your server's mods directory.
  3. Restart the server.

Passwords are saved in the usernamecache.json file.
