We have an office 365 E3 subscription and would like to implement two-factor authentication. We have DirSynch running but no ADFS.
I notice there are settings in the Microsoft tenant portal which allows you to configure users to use 2F. Is it simply a case of configuring it for the appropriate users and the 2F infrastructure / process is managed by O365 or are there any other requirements like having ADFS?
I noticed you can have text message, phone call or app verification. App would be preferred - where's the app for that?
