CrossForward – Hybrid Authentication Bridge
CrossForward is a lightweight, high-performance backend companion plugin built for proxy-based authentication systems. It runs directly on Spigot, Paper, and Purpur servers and acts as a real-time security layer that controls player behavior until authentication is completed through your proxy.

Unlike traditional authentication plugins, CrossForward does not store passwords, manage databases, or perform online checks. Its only purpose is to enforce security rules inside your Minecraft world based on instructions received from your proxy.

How It Works

When a player joins your network:

• The proxy identifies the player type (Premium or Cracked)
  
  
• If the player is not authenticated, a secure LOCK instruction is sent
  
  
• CrossForward instantly applies full restrictions
  
  
• After successful authentication, an UNLOCK signal removes all limits
  

This creates a seamless, secure bridge between your proxy and backend servers.

Built for Hybrid Networks

CrossForward is optimized for servers that support both account types:

• Premium players: Join and play instantly without login commands
  
  
• Cracked players: Secured automatically until they complete login or registration
  

This improves retention while maintaining strong security.

Security Lockdown System

When active, CrossForward enforces a total restriction mode:

• Player movement is frozen
  
  
• Chat and commands are blocked
  
  
• Block breaking and placing are prevented
  
  
• Inventory interaction, item drops, and pickups are disabled
  
  
• PvP and entity damage are cancelled
  
  
• Visual effects such as blindness and slowness are applied
  

This protects your network from bots, griefing, map leaks, and exploit abuse.
