I use native Outlook on my Mac for work, connected to an Office 365 mailbox, and whenever I change my password, native Outlook pops up a little webview (instead of native username/password widgets) with our ADFS SAML flow [0]. We use Duo Security as our MFA solution on another SAML IdP we have (not ADFS, but Shibboleth), and I don't see any reason why it wouldn't work within that Outlook webview in the event that we hooked it all up [1]. We also use some native Android/iOS apps (vendor apps, not in-house) where users log in with SAML, and thus could use Duo MFA. TL;DR: web-based authentication is not just for full-fledged browsers that users type URLs into.
