BasicAuth

A lightweight authentication mod for offline Minecraft servers. Protect your server with password-based login/registration, no client-side mod required.

Features

• Password-protected accounts — players must /register and /login before they can interact with the world.
• Locked out until authenticated — players who haven't logged in are frozen in place (or teleported to a configurable waiting area), can't break/place blocks, interact, attack, take damage, or chat.
• On-screen reminders — a fading on-screen subtitle nags unauthenticated players to log in or register every few seconds.
• Login timeout — auto-kicks players who take too long to authenticate.
• Brute-force protection — kicks after too many failed /login attempts.
• Reconnect grace period — players who disconnect unexpectedly (crash/network drop) while logged in can reconnect from the same IP within a configurable window without needing to log in again.
• Waiting area — optionally teleport unauthenticated players to a fixed location instead of freezing them where they joined, then return them to their last known position after logging in.
• Admin tools — reset a player's password, unregister an account, or list all registered accounts, right from the console or in-game.
• Fully configurable — timeouts, password length, failed-attempt limits, and more, adjustable in-game via the Mods menu or in config/basicauth-common.toml.
