🔐 Authentication

The app uses JWT (JSON Web Tokens) for authentication:

2. Server generates JWT token
3. Token stored in localStorage (frontend)
4. Token sent in Authorization header for protected routes
5. Backend verifies token with authMiddleware

Example:

Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...
