Share Description
This course provides a comprehensive, hands-on guide to implementing secure and robust authentication and authorization in your JavaScript applications using Auth0. You will learn how to move beyond basic login forms and leverage a powerful, production-ready identity platform to manage users, control access to protected resources, and implement modern security standards like OAuth 2.0 and JSON Web Tokens (JWTs). The curriculum is project-focused, guiding you through the process of setting up an Auth0 account, configuring your application, and writing the necessary client-side and server-side JavaScript code to create a complete authentication and authorization solution from scratch.
Topics This Course Covers
- Introduction to Auth0: Understand the fundamentals of Identity as a Service (IDaaS) and the core features of the Auth0 platform.
- Setting Up Your Auth0 Application: Learn to configure a new application in the Auth0 dashboard, including setting up callback URLs and social logins.
- Implementing User Authentication: Integrate the Auth0 Lock widget and the Auth0.js library into your front-end application to handle user login, sign-up, and logout.
- Working with JSON Web Tokens (JWTs): Learn how to receive, validate, and decode JWTs to securely manage user sessions and identity information.
- Protecting API Routes: Implement server-side middleware in your Node.js/Express.js backend to protect API endpoints, ensuring only authenticated and authorized users can access them.
- Role-Based Access Control (RBAC): Discover how to assign roles and permissions to users within Auth0 and enforce access control rules in your application.
- Calling a Protected API: Make secure API requests from your client-side application by attaching the user's JWT as a Bearer token.
Who Will Benefit From Taking This Course
- JavaScript Developers: Frontend, backend, and full-stack developers who want to learn how to properly secure their web applications.
- Web Developers building SPAs: Engineers working with frameworks like React, Angular, or Vue.js who need to implement user authentication.
- Aspiring Security Professionals: Individuals interested in learning the practical application of modern authentication and authorization standards.
- Node.js Developers: Backend engineers who want to learn how to secure their APIs and manage user access effectively.
Why Take This Course
In today's digital landscape, application security is not a feature it's a fundamental requirement. Building a secure and scalable authentication system from scratch is a complex and error-prone task. This course teaches you how to offload that complexity to a specialized service like Auth0, allowing you to implement industry-standard security practices quickly and correctly. By completing this course, you will gain a highly valuable and in-demand skill set, enabling you to build more secure, professional, and production-ready applications, giving you a significant advantage in the job market.
