Whether you develop web applications or mobile apps, the OAuth 2.0 protocol will save a lot of headaches. This concise introduction shows you how OAuth provides a single authorization technology across numerous APIs on the Web, so you can securely access users’ data—such as user profiles, photos, videos, and contact lists—to improve their experience of your application.
Through code examples, step-by-step instructions, and use-case examples, you’ll learn how to apply OAuth 2.0 to your server-side web application, client-side app, or mobile app. Find out what it takes to access social graphs, store data in a user’s online filesystem, and perform many other tasks.
- Understand OAuth 2.0’s role in authentication and authorization
- Learn how OAuth’s Authorization Code flow helps you integrate data from different business applications
- Discover why native mobile apps use OAuth differently than mobile web apps
- Use OpenID Connect and eliminate the need to build your own authentication system

I've been looking for an OAuth 2.0 book for a while. The specification is still being developed while, at the same time, big Internet players like Google, Facebook, Yahoo, or Twitter are already using some flavor of it. Although as a developer you'll eventually rely on a library to abstract most of the complexity, you still want to understand the big picture. And because OAuth 2.0 is still an ongoing process, the situation is a bit of a mess right now where each authorization server is implementing different revisions with subtle differences.
This is where this book comes in. In about 60-70 pages it clarifies the current situation. It starts providing a historical introduction to the protocol and how it's related with initiatives pre-OAuth 1.0 and with OAuth 1.0 itself (removal of proprietary technologies, improved security). You'll learn the rationale behind this revision (new client profiles in particular) and some of the key features still under discussion. In particular "signatures", where Eran Hammer, the protocol editor, is openly opposed to not including them (and after reading his thoughts, I think he's right).
One chapter I specially loved is the one dedicated to OpenID Connect, the next evolution of OpenId. I've seen developers confused about the differences between OAuth (authorization) and OpenID (authentication) and this book differentiates them well. Interestingly, although they still keep different purposes, the new OpenID Connect will now be developed on top of OAuth-which makes sense, as you'll find out in the book.
The code accompanying the text is just fine. You'll see some actual implementations of the workflow in PHP and JavaScript that are easy to read (even a Google App Engine Python at the end - which I appreciate).
