Summary

In this chapter, we took an introductory look at what OAuth 2.0 is and how it is used all around us. We discussed the benefits that this protocol gives us and even looked at the kind of adoption that has taken place in the industry. It has become one of the most, if not the most, used and adopted authorization protocols on the Internet due, in large part, to the power that it gives application developers, start-ups, and corporations alike, to share information.

In the next chapter, we will look at how OAuth 2.0 provides these benefits by looking at how OAuth 2.0 actually works under the hood. Get ready!
