Do you know any way to implement MFA within a Web Api using Identity server?

Something like this https://auth0.com/blog/introducing-the-mfa-api/#Example--A-CLI-App-with-MFA

I've had hard time customizing identity server to do this. The simple task of returning an mfa_token from ResourceOwnerPassword grant with Grant Store support for cleanup seems overwhelming.
