Description

TMT Password System is a lightweight server-side authentication mod for NeoForge 1.21.1. It requires players to register and log in before they can play, and enforces a strict anti‑bruteforce rule: 3 failed login attempts = 30‑minute ban, effectively protecting your server from unauthorised access.

Features

  • Player registration with a password

  • Login system for registered players

  • Password change functionality

  • Blocks player movement, interaction, and item usage until logged in

  • Prevents chat messages and most commands (except login/register/change‑password) before authentication

  • Anti‑bruteforce: 3 incorrect attempts result in a temporary 30‑minute ban

  • SHA‑256 password hashing (no plain‑text storage)

  • Detailed logging of all authentication events (logs/tmt_password.log)

Commands Summary

 
 
Command Description
/register <password> <repeat> Create a new account. Password length: 1–20 characters. Example: /register myPass123 myPass123
/login <password> Log in to the server. Example: /login myPass123
/mispas <old> <new> <repeat> Change your password. Example: /mispas oldPass newPass newPass

How to Use

  1. Install the mod on your NeoForge server (in the mods folder).

  2. When a player joins, they are put into spectator mode, blinded, and slowed – unable to move or interact with the world.

  3. New players must use /register to create an account; registered players use /login to authenticate.

  4. After successful login, the player is restored to survival mode and can play normally.

  5. All passwords are stored securely in config/tmtpassword/passwords.json (hashed).

Installation
