Secure User Sign-Up with Express, Node.js, and Auth0

Every modern web application needs a secure way to register and authenticate users without compromising sensitive credentials. Building authentication from scratch can be risky, which is why leveraging industry-standard identity platforms is essential for modern developers. In this course, you will learn how to integrate Auth0 with a Node.js and Express backend to handle user sign-ups and logins securely. You will transition from understanding basic web security concepts to implementing a fully functional, secure authentication flow. What you will learn: - Understand core authentication concepts, including OAuth 2.0, OpenID Connect, and token-based security; - Configure a secure Node.js and Express application structure using modern environment variable management; - Integrate Auth0 to handle user registration, login, and logout processes seamlessly; - Implement secure session management and protect specific application routes from unauthorized access; - Apply essential security middleware to safeguard your Express application against common web vulnerabilities; - Practice writing clean, readable asynchronous JavaScript code for backend routing. The course begins with foundational authentication terminology and setup, then guides you step-by-step through configuring Auth0, writing Express middleware, and securing application routes. This course is designed for beginner backend developers and web enthusiasts who want to learn secure authentication; basic familiarity with JavaScript and Node.js is helpful but no prior security experience is required.
