TAuth
TAuth requires players on a Forge 1.20.1 server to log in or register before they can act, with secure password storage and admin tools.
What it does
Until a player completes authentication, the server holds back the usual actions: talking in chat, running most commands, walking around, using items, picking things up, opening inventory and taking damage are all restricted. Players register with a password through /register and sign in with /login, and operators can reset a password with /resetpasswd. Login timeouts and a cap on failed attempts are configurable.
Passwords are stored using PBKDF2WithHmacSHA256. An optional shortcut lets a known device sign in without retyping the password, and it can be paired with the password check. When LDLib is present, the client gets a graphical login screen, and migration tools help servers move existing accounts over.
Server owners install it, and players can join with or without it. It depends on Cloth Config API and Kotlin for Forge, and LDLib is optional. Builds exist for Forge 1.20.1 only, with 0.2.0-beta.2 as the latest file, released under the MIT License and open source.
Key features
Login and registration gate
Players must register or log in before most actions are allowed, and the gate lifts once authentication completes.

Passwords are stored with PBKDF2WithHmacSHA256 rather than in plain text.
Operator password reset
Operators can reset a player's password with the resetpasswd command.
Configurable login limits
Login timeout and the maximum number of failed attempts can be set in the configuration.
Optional login GUI
With LDLib present, the client shows a graphical login screen.
Migration tools
Migration tools help servers move existing player data into TAuth.

How it compares
SAuth is server-side only, under the MIT License, and built for 1.20.1 like TAuth, so players can join without installing it. DAuthentication is client and server, for 1.20.1 as well, and is not open source under All rights reserved. The Best Login needs both sides for 1.20.1 and is open source under the MIT License, while PasswordGate covers 1.20.1 – 1.21.1 for Forge and NeoForge under the Apache License 2.0.
