? What is FAPI 2.0 Message Signing?

Simply put, it is a technology that makes the exchange of money and important data more secure!

? It is an evolution of FAPI, which is used in open banking and open data. By adding a “digital signature” to a message, it lets you:

  • ✅ Verify whether the message is authentic
  • ✅ Know whether it has been tampered with along the way
  • ✅ Prove who sent the message

? Why is this important?

Today, billions of people use OpenID Connect, and over the past 5 years FAPI has become the de facto standard for open banking.

In other words, when you manage money in a banking app or securely share data between different services, you are benefiting from this technology!
