The FAPI security profile from the Open ID Foundation is very often associated with financial applications. The truth is, that it describes security enhancements that can benefit any industry. In fact, the working group changed its name from Financial-grade API to FAPI so that it is not so directly connected with finance. In this talk, I will demystify the FAPI security profile. I will explain the vulnerabilities OAuth apps face and how enhancements introduced in the profile allow us to address them. I will show that you can easily benefit from the profile regardless of the industry you work in.
