AuthAnvil

Added support for Folia servers.

🔐 AuthAnvil | Anvil GUI Login Plugin

Say goodbye to chat-based commands. AuthAnvil provides an intuitive and secure login experience using the vanilla anvil interface. Supports offline/premium players and is highly configurable.

✦ Core Features

• Anvil GUI Login: Enter your password directly in the anvil interface — clean and simple.
• Two-Step Registration: Requires entering the password twice to ensure accuracy.
• Premium Auto-Login: Verify premium players via Mojang or LittleSkin API and let them in automatically.
• OP Bypass: Admins can configure OP players to skip the login process.
• Custom Middle Slot: The middle slot of the anvil can be turned into a customizable command button (e.g., help, menu, etc.).
• Session Persistence: After logging in, players can rejoin without re-authentication for a configurable time.
• Anti-ESC Close: The login GUI cannot be closed with ESC, ensuring security.
• Fully Configurable: All messages, sounds, rules, and timings can be adjusted via config.yml.
• Hot Reload: Use /authanvil reload in-game to apply configuration changes instantly.

📥 Quick Start

1. Place AuthAnvil-2.0.0.jar into your server's plugins folder.
2. Start the server, and plugins/AuthAnvil/config.yml will be generated.
3. Edit the configuration file to your needs.
4. In-game, run /authanvil reload to reload the config (or restart the server).
