Multi-factor authentication has been available, at least for users with administrator roles assigned, in Office 365 since June 2013. The problem is that there is a confusing warren of options and configurations that greatly affect the MFA experience an Office 365 user will, or will not, see. In this blog post, I will explain what configurations you need and what MFA experience you will get based on those configurations.
The Problem With Office 365 MFA
I find when my customers think about MFA, they are thinking about the experience they have on a VPN, or maybe the experience when using MFA to sign into their workstations in the morning. They are thinking of protecting a “single sign-on” experience with two factor authentication.
