🛡️ Authentication System with IP Restriction & Session Monitoring

📌 Project Overview

This project is a secure authentication system built with Node.js, Express, MongoDB, and Socket.IO. It restricts users to login only from their registered IP address, and automatically logs them out if an unauthorized login attempt is detected.

🚀 Features

  • JWT Authentication (Token stored in HTTP-only cookies)
  • IP-based login restriction (User must log in from their registered IP)
  • Session Monitoring (Real-time alerts for unauthorized access)
  • Auto-logout on unauthorized login attempts
  • Bootstrap-powered UI
  • EJS-based dynamic pages
  • Socket.IO for real-time alerts
