Part 1: Introduction to Auth and OpenID Connect

This introductory session sets the stage for why OAuth is important and what problem it solves. We’ll clear up the confusion between OAuth and OpenID Connect and cut through the jargon. You’ll learn some background on why OAuth was created, why handling passwords directly is dangerous, and the difference between authorization and authentication. We’ll introduce the different roles involved in the OAuth flows, and cover the basics of the Authorization Code flow with PKCE.
