OAuth 2.0: Getting Started in API Security (API-University Series Book 1)

Book helps to understand better scenarios and actors , involved into authentication process. It good enough for understand the “big picture” in short time and also touches important “little details”. Diagrams are very important part for good understanding.

A cheat sheet book to quickly understand Oauth, really helped me to move forward, now I read the rfc and don't get scared because of so much jibber jabber. I'm putting 4 stars because I found 2 errors and I could never download the promised oauth cheat sheet from the page

I bought this book from Amazon directly and never saw it "live" in a bookstore. My warning - it is a very small book. It's 70 pages long, but the font is huge and most of the pages are half empty. They really tried to make it look bigger at least at the first glance - didn't help, though. The content is OK, but you can read a Wikipedia article on OAuth instead of this book. It should have been a chapter in a book on security; by itself it looked like a joke when I got it in the mail. I am giving it 3 stars, not less, because, once again, the content is OK and it does give you OAuth overview. No code examples, just diagrams and HTTP requests, but that was enough for me. However, I still feel a bit stupid for actually paying money on something I could read up on the Internet for free.

Clear, and precise. Yes, it's short - but one of clearest guides you will find anywhere. Also like that it's language agnostic and focused on oauth and the flow itself. A lot of explanations clutter themselves with a cumbersome / blackbox / "hey it just works!" implementation libraries.

I thought this was a very good book to explain the principles of OAUTH2. What is helpful is the way the author describes OAUTH and provides very clear explanations and a helpful cheat sheet. Recommended to anyone who is interested in using OAUTH on any federation integration project.

There are quite some good publications on OAuth 2.0 and this introduction written by Matthias Biehl is one of the best. If you want to get up to speed on OAuth quickly and don't want to wade through a 300+ page book, you cannot go wrong with this book. The diagrams it contains are very helpful in grasping the overall concepts. If I could give it 6 stars, I would. In short: it's a gem.

Looked at countless videos on oAuth 2, but none of them made this clear. This book changed all that. Crystal clear now.

This book provided a nice overview of OAuth as the author states. I came across some duplicate phrases/words which the author should clean up.

The book is small, but it could be smaller. It is written in a very large font, which makes its reading annoying.

Totally waste of time..full theory based..

Great an concise introduction abour oAuth needed to create API for detachable architectures

Livro simples e conciso na explicação do fluxo OAuth. Ótima leitura pra quem estiver buscando desbravar os conceitos de autorização/autenticação.

I finished this book in the time it took to complete two commutes. It's a comprehensive and simple guide to OAuth2 and how it can be used to protect APIs. It also mentions Open ID and the SAML2 bridge to make SAML2 and OAuth2 interact. The book also provides a OAuth2 cheat sheet that can be printed and pinned on every team's wall with the various sequence diagrams depicting the various OAuth2 flows.
