OAuth 2.0, also known as Open Authorization 2.0, is an authorization protocol that grants applications with fine-grained access to resources on another host.

In this course, you’ll first get an introduction to the OAuth 2.0 protocol, its components, the different kinds of access the resource owner can provide to the client, and different types of OAuth workflows. Then, you will learn to set up a project on the Google Cloud Platform and create authorization credentials. You’ll also look at a guide on how to use the client credentials to generate tokens and use them to access user resources. You’ll learn to create a developer app on Facebook Developers Dashboard, fetch the authorization credentials, and then access the resources of Facebook users with the help of OAuth 2.0 access tokens.

By the end of the course, you’ll have a thorough understanding of the OAuth 2.0 protocol and its components. You’ll also have hands-on experience building a React application to access user resources at Google and Facebook.
