How do Full Stack Developers handle user authentication and authorization?

Full Stack Developers handle user authentication and authorization by utilizing various tools and techniques to ensure secure access to web applications. This process involves verifying the identity of users and granting or denying access based on their permissions. Developers use frameworks like **Passport.js** and **OAuth** to implement authentication and integrate with various authentication providers like social media platforms or third-party services. Additionally, they use **JSON Web Tokens (JWT)** for session management and **Role-Based Access Control (RBAC)** to define user roles and permissions. Full Stack Developers also employ **encryption** and **hashed passwords** to protect user data. They follow best practices like input validation, secure session management, and keeping sensitive information stored securely. Overall, Full Stack Developers employ a combination of backend and frontend techniques to handle user authentication and authorization effectively.
