FYI: configured GAE + Shibb IdP + Google MFA push

I’m a tad confused, over here we have IdP + Duo -> Google and it seems to do what we want (2FA to get access). Where is the gap that led you to instead go this route?

2FA for email is a management priority, so IdP first factor and Google's 2nd factor addresses that specific priority.
That holds out hope for SSO via single IdP deploying 2FA for Google for entire UA via Google's 2FA and Duo, selectively, for vastly smaller number of high risk accounts or services. While not ideal, the alternative (which may still be what is deployed) is Google authentication and 2FA for Google apps, Shibb IdP for others, most of which are not 2FA protected.

So as long as the only thing you want 2nd factor for is Google’s own services, that will work. Is that all you needed it for?
