🔒 Auth Guard

Auth Guard is a lightweight, easy-to-use authentication plugin designed for Minecraft servers that run in offline mode. It ensures that players log in securely and protects their accounts from unauthorized access.

✨ Features:

• 🔐 Secure registration & login system

• 🗄️ Simple built-in commands for database management (e.g. remove player data)
• 🎯 Captcha verification to prevent bots
• 🔄 Allows players to change their passwords anytime with /changepass
• ⏰ Automatic kick if player doesn't log in within set time

• ⚙️ Completely configurable and easy to setup

📊 This plugin uses bStats to collect anonymous usage data to help improve it.

🔧 How it works:

1. When a new player joins, they are required to register with a password using /register.
2. Returning players must login using /login.
3. Players who fail to login within the configured timeout are automatically kicked.

5. All messages are customizable and support MiniMessage formatting.
