By: Adolfo Eloy Nascimento

Overview of this book

OAuth 2.0 is a standard protocol for authorization and focuses on client development simplicity while providing specific authorization flows for web applications, desktop applications, mobile phones, and so on. This book also provides useful recipes for solving real-life problems using Spring Security and creating Android applications. The book starts by presenting you how to interact with some public OAuth 2.0 protected APIs such as Facebook, LinkedIn and Google. You will also be able to implement your own OAuth 2.0 provider with Spring Security OAuth2. Next, the book will cover practical scenarios regarding some important OAuth 2.0 profiles such as Dynamic Client Registration, Token Introspection and how to revoke issued access tokens. You will then be introduced to the usage of JWT, OpenID Connect, and how to safely implement native mobile OAuth 2.0 Clients. By the end of this book, you will be able to ensure that both the server and client are protected against common vulnerabilities.

Using Google OpenID Connect with Spring Security 5

OAuth 2.0 protocol and OpenID Connect are both stable specifications that are evolving through additional specifications. On the other hand, frameworks that implement both technologies are always changing quickly with regard to new requirements, famous paradigms, new versions of languages, and even to improve maintainability.

That's our case with Spring Security and Spring Security OAuth2. At the time of writing this, all the projects related to OAuth 2.0, OpenID Connect, and social connectivity are being condensed within Spring Security 5. Spring Security 5 brings in lots of advantages, improving the way we add security to our applications. But at the moment, we can just count with client implementations for OAuth-related technologies. Through this recipe, let's explore how to authenticate users with Google OpenID Connect.
