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

Install the mod on your NeoForge server (in the mods folder).
When a player joins, they are put into spectator mode, blinded, and slowed – unable to move or interact with the world.
New players must use /register to create an account; registered players use /login to authenticate.
After successful login, the player is restored to survival mode and can play normally.
All passwords are stored securely in config/tmtpassword/passwords.json (hashed).
