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.

Dynamic client registration

This recipe will present you with steps to improve an Authorization Server by adding support for dynamic client registration. This profile might be critical for native clients that require to be deployed without packing client credentials as part of the application. It's recommended that mobile client applications use dynamic registration to increase safety.

Getting ready

To run this recipe, you will need Java 8, Maven, MySQL, and your preferred IDE. As we will use Spring Boot, it's also recommended that you create an initial project using Spring Initializr.

How to do it...

The next steps will present you with how you can create an Authorization Server that implements a use case from the dynamic client registration profile:

  1. Create the project using Spring Initializr. Go to and fill out the form using the following data:
    • Set up the Group as com.packt.example
    • Define the Artifact as dynamic-server and add Web, Security, JPA, and MySQL as dependencies...
