Day 14 – Authentication with JWT in MERN Applications

Leave a Comment / MERN Stack Developer /

Introduction Authentication is a cornerstone of any secure MERN application. JWT (JSON Web Token) is a widely adopted method to manage user sessions and verify identities across frontend and backend systems. Unlike traditional session-based authentication, JWT enables stateless, scalable, and secure authentication, making it ideal for modern MERN apps. CuriosityTech.in emphasizes hands-on JWT implementation, ensuring […]
