Introduction to OAuth 2.0 and OpenID Connect
This page contains the resources for the talk titled 'Introduction to OAuth 2.0 and OpenID Connect'.
OAuth 2.0 is likely one of the most complex aspects of modern web applications. It is often mistakenly assumed that OAuth 2.0 offers authentication and authorization. Instead, OAuth 2.0 only offers delegation. To make matters more complicated, there are at least six different OAuth 2.0 flows, each for a particular purpose. On top of that, OpenID Connect (OIDC) redefines some of these flows to enable authentication explicitly.
In this talk, we will clear up the confusion about OAuth 2.0 and OIDC. We will explain the purpose and properties of most relevant flows. We explore how to use OAuth 2.0’s delegation mechanism to enable authorization on a backend. Finally, we will look at using OIDC for end-user authentication with a third-party provider. At the end of this talk, you will have a solid understanding of OAuth 2.0/OIDC and how to use it in your applications.

Hi, I'm Philippe, and I help developers protect companies through better web security. As the founder of Pragmatic Web Security, I travel the world to teach practitioners the ins and outs of building secure software.
Talks and workshops
Security is often about small nuances. In my articles, I dive deeper into various security topics, providing concrete guidelines and advice. My articles also answer questions I often get while speaking or teaching.
Getting security right is all about knowledge. I strongly believe in sharing that knowledge to move forward as a community. Among my resources, you can find developer cheat sheets, recorded talks, and extensive slide decks.
