Introduction to OAuth 2.0 and OpenID Connect
Philippe De Ryck
Monday June 13, 09:00 - 10:30
Short description
OAuth 2.0 and OIDC are confusing, which often results in confusion and implementation mistakes. In this session, we explore the purpose of these technologies and the current best practices of using them.
Abstract
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, while it only offers a delegation mechanism. On top of that, OpenID Connect (OIDC) redefines some of these flows to enable authentication explicitly.
In this session, we will clear up the confusion about OAuth 2.0 and OIDC. 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.
Key takeaway
A solid understanding of OAuth 2.0/OIDC best practices and how to effectively use these technologies in your applications.
