JWT-Based Authentication:
How it works: JSON Web Tokens (JWT) are encoded tokens containing user information and digital signatures to verify their authenticity. When a user logs in, the server creates a JWT and sends it to the client.
Usage: The client stores the JWT (usually in local storage or a cookie) and includes it in the header of subsequent requests.
Pros: Stateless (no need for server-side storage), easily scalable, supports cross-origin resource sharing (CORS), suitable for microservices architectures.
Cons: Tokens cannot be invalidated before expiration without additional complexity (blacklisting, short-lived tokens), potential security risks if not implemented correctly (e.g., token leakage).
