bingus-auth

A simple, lightweight authentication mod for Minecraft 26.1 Fabric servers.

Features

  • Password authentication for Java players (Argon2 hashing)
  • Teleports unauthenticated players to a configurable spawn point to hide their real coordinates (as of 1.0.0 you need to edit the source)
  • Blocks all packets (movement, chat, interactions) until authenticated
  • Per-session state, logging out deauthenticates the player

Commands

Command Description
/register <password> Register a new account
/login <password> Login to your account
/l <password> Alias for /login
/deletepassword <username> (Admin) Delete a player's password and kick them

Requirements

  • Minecraft 26.1
  • Fabric Loader 0.18.5+
  • Fabric API
  • Fabric Language Kotlin
  • Java 25

Installation

Drop the jar into your server's mods/ folder. No configuration file needed. Spawn coordinates default to 0, 400, 0 in the overworld and can be changed in AuthConfig.kt before building.

Data

Player passwords are stored in config/bingus-auth/data.json as Argon2 hashes. Do not edit this file manually!

Floodgate / Geyser

Bedrock players are detected by their UUID (Floodgate assigns UUIDs with mostSignificantBits == 0). They are automatically authenticated without needing a password.

Notes

  • This mod is purpose-built for one server and is still in beta
  • No config file UI, change settings by editing the source and rebuilding as of now
