Login Security - Panda
by guarda_panda
Login Security - Panda, a NeoForge server mod, requires players to log in or register before they can act, and limits how many accounts one IP address can hold.
What it does
Until a player authenticates, the mod freezes movement and blocks interactions with items, blocks and chat, so an unauthenticated account cannot take actions in the world. Password checks allow a configurable number of attempts, and the minimum password length is 4 characters by default.
An IP registry tracks the accounts linked to each address, and a configurable account limit per IP discourages multi-accounting. Admin tools are included for managing the server. The mod is server-side only, so players join without installing anything, and it is published for NeoForge on 1.21.1 and 1.21.4 with release 1.0.1 as the latest file. Its source code and issue tracker are public, but the code is under All rights reserved and is not open source.
