Recent developments in OAuth

Short description

This session will introduce the audience to a couple of extensions to the OAuth standard that that help to build more secure systems in an easier and more interoperable way.


OAuth 2 has long grown beyond the original scope in the area of social networks. Nowadays, it is well established as THE mechanism for protecting access to all kinds of APIs, which includes security critical areas like finance or health.

To facilitate such use cases, the OAuth framework has been extended with a couple of extensions, such as Rich Authorization Requests (RAR) and Pushed Authorization Requests (PAR). This session offers an insight into those extensions, along with the FAPI 2 security and interoperability profile for OAuth.

Key takeaway

OAuth 2 was improved and simplified a lot in the last years.
