Learn to use Oauth2 to add third-party authentication in Spring web applications.

Web Authentication and Authorization

This module will show you what Oauth2 is, why it's important, and how to use it effectively. We'll start with an overview of Oauth2 in general and then explore its different types of grants, including password, authorization, refresh token, and more. All these concepts are backed by hands-on exercises. We'll get to practice creating cross-origin resource sharing policies and custom user-principal. We’ll also learn about the configuration of the authorization server to send login credentials via JSON. By the end of this module, we will have the foundations to add a proper authentication system to our application.
