Limited Offline Mode Paper

Let specific players join your online-mode Paper server without Mojang authentication — no proxy, no config changes, no server restarts required.

Perfect for server admins, developers, and staff who need emergency or testing access without exposing the entire server to offline mode.

Features

  • Whitelist by username — add names to a simple text file, done
  • Player groups — batch players into named groups and toggle them on/off with a command
  • Persists across restarts — config is file-based, nothing is lost on reboot
  • Live reload — /lomgroup group reload applies changes instantly, no restart needed
  • No proxy needed — works directly on Paper, no Velocity or BungeeCord required
  • Full login event support — fires AsyncPlayerPreLoginEvent and all standard Bukkit events normally

Quick Start

  1. Drop the JAR into your plugins/ folder
  2. Start the server — allowed-users.txt is created automatically
  3. Add usernames to plugins/LimitedOfflineMode/allowed-users.txt
  4. Players on the list can now join without Mojang auth

Commands

Command Description
/lomgroup group add <group> <players> Add players to a group

Forked from moritxius-matsuda/LimitedOfflineMode (original Velocity/BungeeCord plugin). This is a full rewrite for Paper by chank_op.

⚠️ For administrators and developers only. Do not use to allow cracked clients or bypass Mojang auth for regular players. You are responsible for your own EULA compliance.
