Skype iOS client and MFA Supportability
See https://support.microsoft.com/en-us/help/3126604/skype-for-business-mobile-users-can-t-sign-in-when-modern-authentication-is-enabled
It will explain a lot :)
Greetings,

Yes, that is the same article that I quoted at the bottom of my question but I referred to it as https://support.microsoft.com/en-us/kb/3126604 (but it links to the same place your URL points to).
According to that article, The iOS mobile client for Skype for Business should be compatible with MFA but instead it requires me to put in an App Password.
Joe Stocker, I had the same problem as you after enabling MFA on my user and enabling Modern Authentication on SfB Online + Exchange Online (IOS app right now 6.11.1.310). I agree with you, according to the KB3126604 , it's quite clear that if you're a pure online Office 365 tenant, MFA should work on IOS and Android.
For me, the problem was that I had played around with the app settings. On the logon screen, check Advanced Options before signing in - I had a different old User Name entered there at the top.
- The username field in Advanced Options was already empty for me, so that did not help me.
