🔐 FrozenAuth

📦 Plugin Info

A secure authentication plugin for Paper/Folia/Purpur servers with GeyserMC/Floodgate support. Players are required to register and log in with a password before they can move or interact with the world. Includes a private limbo platform, countdown bossbar, join-message hiding until authenticated, and a GUI-confirmed password reset flow.

✅ Versions / Compatibility / Software Support

• API Version: 1.20
• Built against: Paper API (targeting the 1.26.x line), Java toolchain, Maven build
• Server software: Paper, Folia, Purpur
• Folia support: ✅ Supported (folia-supported: true)
• Soft dependency: Floodgate (optional — enables full GeyserMC/Bedrock Edition support)
• Automatic proxy-auth detection: If a verification layer such as Velocity/BungeeCord with IP forwarding, or a plugin like FastLogin, is present in front of the server, FrozenAuth automatically defers to it — no config changes needed.

🔐 Permissions

⌨️ Commands

Full tab completion is included for all commands.

🎯 Uses

• 🛡️ Requires a password before players can play, protecting accounts and preventing impersonation.
• ✅ Microsoft (premium) accounts and Bedrock Edition players don't need to login or register — they're welcomed through automatically.
• 🧊 Sends players who still need to authenticate to an isolated, private per-player limbo platform (5×5, barrier-blocked) until they finish.
• ⏱️ Configurable authentication timer with a live bossbar countdown; players who run out of time are kicked with a custom title/subtitle.
• 🙈 Optionally hides the "player joined" broadcast until the player has actually authenticated — if they disconnect first, no one ever saw them join.
• 🚫 Freezes movement and applies Blindness during the auth period so players can't peek at or wander through the world before logging in.
• 🎨 Fully customizable messages, titles, bossbar, and GUI text, with hex color (&#RRGGBB) support throughout.
• 🌍 Smart post-auth teleport: sends first-time players and anyone whose last location was the spawn world to spawn, and restores everyone else to their exact last location.
• 🎮 Separate, configurable welcome titles and chat messages for Bedrock Edition and Microsoft (premium) players.

⚙️ Key Config Areas (config.yml)

• auth.* — timer length, blindness, movement freeze, join-message hiding
• limbo.* — spawn world used for post-auth teleport logic
• bedrock.* — Bedrock Edition spawn world, welcome title, and join message
• bossbar.* — countdown bossbar enable, title, color, style
• titles.* — join titles/subtitles shown during the auth period
• messages.* — every user-facing plugin message, including the auth-timeout kick screen
• gui.* — text for the password-reset confirm/cancel GUI
• premium.* — welcome title and join message for Microsoft (premium) accounts 💾 Data & Configuration
• YAML-based configuration with per-world spawn customization
• Persistent player data storage (backward-compatible with v1.x data.yml)
• Reload command for live config updates without restart

🔧 Developer-Friendly

• Maven build system with Java 21 compilation
• Lombok for reduced boilerplate
• Clean, modular architecture
• Extensive javadoc and code comments

Commands

All permissions default to true except frozenauth.reload (op-only).

Configuration Highlights

• Per-world spawn location — customize where players spawn after authentication
• Limbo platform customization — choose outer and center block types (default: glass + enchanting table)
• Auth timeout duration — configure how long players have to authenticate
• Join message suppression — hide join messages until players are authenticated
• Gradient message styling — color-coded authentication prompts and feedback

Bedrock Edition Support

GeyserMC/Floodgate players can register and login using the same commands as Java players. Automatic detection ensures smooth cross-platform compatibility.

What's New in v2.0.0

🔄 Major Rework

• Complete architectural overhaul for stability and performance
• Fixed critical bug: new registrations were leaking limbo platform slots
• Fixed: /register now respects limbo.spawn-world config (previously ignored)
• Migrated from deprecated AsyncPlayerChatEvent to modern AsyncChatEvent

🚀 Performance & Compatibility

• Removed hard LuckPerms dependency that was causing boot failures
• Implemented Folia-safe scheduler for all async operations
• Hardened void chunk generator with explicit biome provider
• Fully compatible with Paper 1.21.4–1.21.11+

🎨 UI Improvements

• Password reset GUI redesigned with black border, gradient styling
• Auth-timeout kick screen now uses consistent gradient branding
• Enhanced limbo platform (5×5 with enchanting table center)

Installation

1. Download the latest release JAR
2. Drop into plugins/ folder
3. Restart server or use /reload
4. Configure plugins/FrozenAuth/config.yml to your needs
5. Restart (or /frozenauth reload) for changes to take effect

If migrating from v1.x: Simply drop your backed-up data.yml into plugins/FrozenAuth/ after installing — all player passwords load normally.

Permissions Matrix

Requirements

• Server Software: Paper/Folia/Purpur 1.20+
• Java: Java 21 (for running the server)
• Dependencies: None required; Floodgate is optional

Support for Verification Layers

If you deploy FastLogin or run a proxy (Velocity/BungeeCord) with real Mojang authentication + modern player forwarding, FrozenAuth automatically uses cryptographic premium verification. Otherwise, it falls back to standard username-based detection — no configuration needed, it adapts automatically.

Known Behavior

• Premium players (registered with Mojang) bypass registration and login automatically
• Unauthenticated players cannot move, use inventory, execute commands, or interact with the world
• Limbo world is completely isolated — other plugins' features (TAB scoreboard, etc.) can be disabled per-world in their configs
• Join/quit messages are suppressed for unauthenticated sessions

Development & Contributions

Built with:

• Paper API 1.21.11-R0.1-SNAPSHOT
• Lombok 1.18.30 (for clean code)
• GeyserMC Floodgate 2.2.2 (optional, soft dependency)
