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.

Oauth2 with Spring Security

Congratulations! You've successfully completed the “Oauth2 with Spring Security” module.

## Summary

This module started with a comprehensive description of the theory behind OAuth2. We covered the various types of grants that manage access to protected resources. The latter half of the module focused on implementing these concepts in practical exercises to give a vivid idea of how authentication works. In the end, we learned how to enable third-party authentication in our applications.

## What's next?

Now that we know how to add OAuth2 authorization to Spring applications, we will learn how to authenticate application users with Okta in the next module, "Authenticating Application Users with Okta in JavaScript."
