Identity, Unlocked... Explained: Season 2, Ep. 1

Torsten Lodderstedt joins the podcast today to talk about his work on Financial-Grade API (FAPI) WG.

January 25, 2021

The Overview

In this episode of Identity. Unlocked, principal architect at Auth0 and podcast host, Vittorio Bertocci, interviews Torsten Lodderstedt. Torsten is the CTO of yes.com and is an all-star contributor to the IETF and the OpenID Foundation. The interview centers on Torsten’s work on Financial-Grade API (FAPI) WG.

FAPI is a security and interoperability profile for OAuth, and it was originally intended for use in open banking scenarios. Torsten explains how FAPI navigates two challenge areas of using OAuth in open banking, what one may find within the FAPI working group initiatives, and the differences between FAPI versions 1 and 2. Further, Torsten delves into some specific macro areas of FAPI and discusses JARM (JWT Secured Authorization Response Mode). He details cryptography measures such as MTLS and their relation to FAPI, his thoughts on the future of FAPI, prominent features in the specifications (such as CIBA, or Client Initiated Backchannel Authentication), and helps listeners interested in FAPI to determine what version might best suit them. Of course, if listeners have to integrate with another system, then they must see what that system can support. But for the listener who owns their own API, Torsten’s general recommendation is to consider FAPI version 2!
