How It Works

First Time Players

1. Player joins the server
2. Teleported to authentication dimension (void space)
3. Registration dialog appears
4. Enter password twice to confirm
5. Automatically returned to spawn location

Returning Players

• Within 12 hours + Same IP: Instant login, no dialog
• After 12 hours OR Different IP: Login dialog appears
• Enter password to authenticate
• Return to your saved location

Commands

• /dialogauth changepass - Change your password
• /dialogauth reload - Reload configuration (admin only)

Configuration

Located in config/dialogauth/config.json:

{
  "authentication": {
    "min_password_length": 4,
    "max_password_length": 32,
    "session_duration_hours": 12,
    "check_ip_address": true
  }
}

Key Settings

• session_duration_hours - How long players stay logged in (default: 12 hours)
• check_ip_address - Require re-login when IP changes (default: true)
• min_password_length - Minimum password length (default: 4)

Localization

Customize all messages in config/dialogauth/lang.json:

{
  "command": {
    "register": {
      "success": "§aSuccessfully registered!"
    },
    "leave": {
      "disconnect_message": "Disconnected"
    }
  }
}

Dialog Customization

All dialogs can be customized in config/dialogauth/dialogs/:

• register/ - Registration dialogs

• changepass/ - Password change dialogs

Note: Dialog changes require server restart.
