Learn to use OAuth2 to add third-party authentication in reactive web applications.

Spring Boot Development for Java Programmers

In this module, we’ll start with an overview of OAuth2 in general and then explore the different types of grants in it including password grants, authorization grants, refresh token grants, and more. All these concepts are backed by hands-on exercises, so we’ll get to practice creating cross-origin resource sharing policies and custom user-principal as well as configuring the authorization server to send login credentials via JSON.

By the end of this module, you will have the foundations in place to add a proper authentication system to your application.

OAuth2 with Spring Security

Congratulations! You’ve 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.

## Takeaways
- We learned how to use the Spring framework in the development process.

- We comprehensively discussed the fundamentals of Spring Boot (auto-configuration, database integration, web services) and its advantages over the conventional architecture.

- We learned all the essential concepts needed to start developing an application using Thymeleaf and Spring Boot.

- We learned how to build a full-reactive system using a programming strategy leveraged by Spring WebFlux.


- We learned how to implement and use the OAuth2 authentication process.
