Bulk enable Multifactor Authentication in Office 365 and configure mobile phones.


I have enabled Multifactor Authentication using phone authentication for a user in the Office 365 portal.  

I am able to use the new app-code to sign to Outlook and OWA.  

My email account in my mobile phone still using the old password I think.  How is the new MFA app-code being applied to it?

Also, how do I enable MFA for group of users?

Have a look of the link above. You need to acquire the appropriate licence before the users can use MFA.
