OAuth2 is a common standard for authentication and authorization. There are a number of different standard flows, but the standards docs leave a lot to the implementor.
In this talk, I'll cover 8 different ways we have seen customers using OAuth in the real world. These include having a standalone local auth server, federation with social or enterprise identity providers, and machine to machine communication. At the end of this talk, you'll know the problems OAuth can help you solve and why you might choose one mode of OAuth over another.
