I know what you are thinking, is this really another guide to OAuth2.0?
There are hundreds of articles and blog posts covering OAuth 2.0, but none of them present the modern, real-world use cases. This guide covers OAuth 2.0 from a real-world perspective and covers modern use cases of the specifications.
This guide is different than most of the others out there because it covers all of the ways that we actually use OAuth. It also covers all of the details you need to be an OAuth expert without reading all the specifications or writing your own OAuth server.
This book is based on hundreds of conversations and client implementations as well as our experience building FusionAuth, an OAuth server which has been downloaded over a million times.
