Cian Allner,

 

Hmmmm, that was what I suspected but I am still prompted to use App Passwords with my Office desktop apps (running Office 365 desktop apps; all patched to the latest version), with my Microsoft 365 account.

 

I have Microsoft Authenticator Passwordless Signin working perfectly when logging into portal.office.com and using Office mobile apps (Mac and Android), but for some reason it's not working with Office dekstop apps on my Windows 10 Business client, even under my Azure AD integrated profile.

My license is Microsoft 365, but perhaps the issue may be that I'm not on Microsoft 365 E3/E5?   How would I check this?

    Thijs Lecomte,  THANK YOU!!

    I'd been going back and forth with Office 365 Support on this issue, and NONE OF THEM, responded with this basic response.   No, Modern Authentication was NOT enabled for my Exchange Online environment, which is obviously a piece of what's impacting my ability to enable passwordless push MFA for native Office 365 desktop apps on a Windows 10 Business / Azure AD integrated user profile.

     

    Again, thank you for the answer to my question.
