How do I integrate Auth0 MFA into a .net Winforms/SQL desktop application?

Hi:

New to Auth0/Okta here.

We have a .Net Winforms application which is supported by a backend SQL DB (either Azure or on prem hosted). Currently we have a simple username/pwd login scheme which authenticates against a user table in the above mentioned DB.

Customers have been requesting that we additionally secure our log in process by adding MFA.
I have looked at a couple of WInforms/WPF examples that I found online. It’s not clear to me how this would fit into our current login/authentication scheme.

Can someone perhaps get me pointed in the right direction with some examples/advice that would be suited to our requirements?

Thanks,
JohnB
