Description
OAuth 2.0 is one of the most widely used authorization frameworks on the web today. Whether you're developing web applications, mobile apps, or APIs, understanding how OAuth 2.0 works is essential for creating secure and user-friendly experiences. This course is designed to help you understand OAuth 2.0 in a clear and practical way, even if you're completely new to the topic.
We’ll begin by exploring the basic concepts of authorization and how OAuth 2.0 fits into the bigger picture of modern web security. You’ll learn how different apps and services can securely share data without sharing passwords, and how access tokens make this possible. As we move forward, you'll see real examples of how OAuth 2.0 is used by popular platforms like Google, Facebook, and GitHub.
This course will take you through the different components of the OAuth 2.0 framework, including clients, authorization servers, and resource servers. We'll break down complex topics like authorization codes, token lifetimes, and refresh tokens in a way that’s easy to understand. You’ll also gain insight into common OAuth 2.0 flows used in real applications, such as the Authorization Code flow and Client Credentials flow.
By the end of this course, you'll have a solid understanding of how OAuth 2.0 works behind the scenes and how to apply it in your own projects. You’ll be better equipped to build secure applications and confidently use OAuth 2.0 in both personal and professional projects
