i was reading this As a Cloud Consultant working with products that are part of the Office 365 and the Microsoft Enterprise Mobility +Security Suite (EMS), I often get a lot of questions about multi-factor authentication (MFA), and how to get started.
blog link Most customers today has a strategy about MFA when employees are trying to access corporate company data from outside the company perimeter. But when customers are using cloud services like Office 365, OneDrive and SharePoint that boundary moves from a physical boundary to the user identity. Therefore the requirement for multi-factor authentication is something that most customers wants to implement as part of their cloud strategy.
review The key to a successful MFA deployment starts by enabling modern authentication. Modern authentication brings Active Directory Authentication Library (ADAL)-based sign in to your Office 365 applications, and without this enabled, end users will have to use “App Passwords”, witch is a true nightmare for any user and it department.

I recommend that you enabled for modern authentication both Exchange Online and Skype for Business, if you want to use MFA.
- Skype for Business Online – OFF by default.
- Exchange Online – OFF by default.
- SharePoint Online – ON by default.
Enable modern authentication for Skype for Business Online
To enable modern authentication for Skype for Business Online, complete the following steps:
Step 1: Install Skype for Business Online, Windows PowerShell Module:

Thanks to @AlexFilipin for reminding me, to add this note to the article.
I have also posted a sample script on Microsoft TechNet Gallery, where all the commands used in this example can be found: https://gallery.technet.microsoft.com/Enable-modern-authenticatio-d7180f99
That’s it… Enjoy!

Thanks! Your solution was the only one that worked!
If I enable MFA for Skype for Business Online, using the powershell method you described, does that mean that EVERY user will be asked to enter a code from a Microsoft Authenticator APP, even though Two Factor Authentication may not be enabled on EVERY Office 365 User Account? Put another way, I only have 10% of my users enabled for Two Factor Authentication in my Office 365 tennant, and I am concerned that if I enable MFA on ‘Skype for Business Online’ via powershell, that it will prevent skype login for 90% of my users who do not enrol for MFA yet. Thank you.
No… MFA is not required if you enable modern authentication. It’s safe to do this.
Thanks very much Ronni

Are there any drawbacks to enabling modern authentication? I can’t imagine that this would affect any other O365 systems, but want to be sure before I enable this in our production tenant.
No. This should not affect any systems. You will only get more options.
Have I understood wrong, when I believe that enabling Modern Auth on SfB will, in fact, enforce it? Resulting in for example 2013 clients being unable to login without setting enableADAL through GPO’s?
Basic Auth. will still work….
This article is awesome! I was spinning my wheels for quite some time just using the instructions provided by Microsoft (they really make you work for it).
Thank you so much!
You’re welcome 🙂
