Description

Are you ready to level up your authentication skills with AWS Cognito and OAuth 2.0?
This hands-on course is designed for developers who want to confidently implement secure, scalable user authentication in real-world web and mobile applications.

You’ll dive deep into OAuth 2.0 workflows, including the Authorization Code Grant with PKCE, and understand how tokens like Access Tokens and ID Tokens work under the hood. With that knowledge, we’ll move into JWT-based authentication, making it easier to implement secure flows in both frontend and backend systems.

Through step-by-step demos, you’ll learn how to:

• Integrate Cognito with React Single-Page Apps (SPA)

• Implement React + Node.js full-stack auth flows

• Enable social login with Google as an Identity Provider

Each concept is backed with hands-on examples, from securing your frontend to building a full authentication server using Cognito.

By the end of this course, you’ll be equipped to implement production-ready authentication using AWS Cognito and OAuth 2.0 with modern best practices.
