• Multi-Language Support: Built-in support for multiple languages (English (UK), Dutch (Belgium))
• Smart Authentication Skip: Skip login for premium accounts or matching IPs (configurable)
• Account Management: Players can unlink Discord accounts, logout, and manage passwords
• Security Options:
  • Max accounts per Discord account limit

Building

Run mvn clean package to build the plugin. The compiled JAR will be in the target folder.

Installation

1. Build the plugin or download the JAR
2. Place the JAR in your server's plugins folder
3. Restart the server
4. Follow the Initial Setup guide above
5. Configure plugins/DiscordAuth/bot-token.yml and config.yml
6. Reload or restart the server

How It Works

First-Time Registration

1. Player joins the server
2. Plugin prompts for Discord User ID or password setup using a dialog
3. If Discord: Bot sends 4-digit code via DM → Player enters code
4. If password-only: Player sets a password
5. Account is registered and player can join

Returning Players

1. Player joins the server
2. If skip rules apply (premium/IP match), player joins immediately
3. Otherwise, player must verify with Discord code or password
4. After verification, player can join
