Quick question: I have a client that would like to integrate DUO 2-factor Authentication with Kratos. Is this possible?

Not really familiar with DUO, but it seems they support WebAuthn and Duo Push (seems like a custom / selfmade implementation). Is there a reason you cant use the native WebAuthn integratioin in Kratos? Or do you want to offer DuoPush instead?

There is a customer of my customer that has a preference for supporting DuoPush. I admit that I am not an expert on WebAuthn--I would have to look all that up. However, the way I have been working with customers is that I provide the hosting for self-hosted Ory products as well as the application services that I build for them based on a service framework I have for building other microservices. My customers often sell THEIR services to other customers up the chain. In this case, that customer must respond to RFP's (in the healthcare space) where security features, etc. must be answered for and validated.
