This article doesn’t want to be the final guide to OAuth 2, but an introduction to the flows that this framework is composed of. You’ll have a look at the four basic flows and some practical scenarios, to understand the involved actors and the detailed behaviors. The goal is to be able to choose a flow that best fits your needs. To make it as easy as possible, the experts will forgive me, we can say that there are four different versions. Or, more correctly, four different flows. OAuth 2 is the totality of these flows. It’s not mandatory to implement them all, but only the ones that you need.
