User authentication and authorization are critical for securing applications. This tutorial focuses on implementing user authentication in Express.js using various strategies, such as session-based authentication with cookies or token-based authentication with JWT (JSON Web Tokens). You’ll learn how to create login and registration endpoints, handle password hashing (using bcrypt), and manage user sessions. Additionally, you’ll explore role-based access control (RBAC) and permissions to authorize user actions.
