# Authentication System
# Role Based Access Control
# Database Schema
# 🔐Authentication and Authorization Backend
A clean, modular authentication system built with **Node.js**, **Express**, and **MongoDB**, supporting secure user registration, login, and protected routes using **JWT** and **bcrypt**. This project demonstrates best practices in backend architecture, request validation, and role-based access control.
---
## 🚀 Features
- ✅ Secure **Signup** & **Login**
- ✅ Password hashing with **bcrypt**
- ✅ **JWT-based** authentication
- ✅ **Get Current User** (`/auth/me`) endpoint
- ✅ Middleware for protected routes
- ✅ Centralized error handling
- ✅ Input validation (middleware schema or manual checks)
- ✅ Optional **role-based** access (admin/subadmin)
