Recent evolutions in the OAuth 2.0 and OpenID Connect landscape

This page contains the resources for the talk titled 'Recent evolutions in the OAuth 2.0 and OpenID Connect landscape'.

Abstract

Ever since the introduction of OAuth 2.0, the framework has been in continuous evolution. The initial specification addressed a strong need for delegation. However, since then, various addendums focus on the needs of modern applications. Today, the suite of OAuth 2.0 specifications supports a broad spectrum of different scenarios. For each of these scenarios makes their security assumptions and defines a set of best practices.

In this talk, we will investigate a number of these recent additions. We look at the recently added “Proof of Key for Code Exchange” (PKCE) flow. We also investigate how it is becoming the default flow for Single Page Applications. We also extensively dive into “Proof of Possession” tokens. Their security properties are significantly better than bearer tokens. Consequentially, everyone should know what they entail, and how to use them. You will walk away with a solid overview of recent evolutions in OAuth 2.0, and where to use them in your applications.
