✅ What I Have Done

• 🏗️ Built a complete authentication system with user registration, login, reset password, and set new password flows.
• 🔒 Implemented JWT-based authentication and route protection.
• 🧩 Used MongoDB with a User model having fullName, email, password, and isEmailVerified fields.
• 📂 Followed a modular project structure for controllers, routes, middleware, and config.
• 🧪 Fully tested all endpoints using Postman. A collection file is included for reference.

🧪 API Testing

• Used Postman to test all routes.
• Included a full test flow:
  • Register → Login → Get Profile (JWT Protected)
  • Reset Password → Set New Password → Login Again
• ✅ The Postman Collection file is included:
  • backend-task-User-Auth.postman_collection.json
