AccProtector
by Hugward
AccProtector adds password registration and login to a Minecraft server, so each account is tied to the player who created it.
What it does
A player who joins for the first time sees a registration menu and sets a password. On later joins a login menu asks for that password before the player can play. The system includes brute-force protection, and the server owner sets how many wrong attempts are allowed before the account is locked. Players can change their password at any time with an in-game command, and server administrators can reset it.
Server administrators manage the mod through a built-in Admin Panel GUI, where security settings are changed without editing files. The panel can make registration mandatory for every player with a single toggle, and it can enable or disable a session timeout that lets trusted players skip password entry for a set period. The mod is built for multiplayer servers. It runs on Forge and NeoForge across 1.20.1 and 1.21.1, and it has to be installed on both the client and the server.
