JWT vs Session Cookies: Which Authentication is Best?
Compare stateless JSON Web Tokens with stateful session cookies to decide the best authentication strategy for your web application.
JWTs enable stateless, scalable authentication
JSON Web Tokens (JWT) store user information directly in the token, allowing servers to verify identity without a central session store. This makes them ideal for microservices and mobile apps.
Session Cookies offer better control and security
Traditional sessions stored on the server allow for immediate revocation and are less susceptible to Cross-Site Scripting (XSS) if configured with HttpOnly and Secure flags.
