If you want to tighten up the security on your Office 365 access, the easiest and cheapest way to do it is by requiring two factor authentication (2FA) using the Microsoft Authenticator App. Microsoft multifactor authentication requires users to enter a username and password along with confirming their identity using an app on their cell phone or tablet.
The video provides Office 365 MFA setup step by step:
This works on PC’s Apple Mac’s and the Microsoft Authenticator runs on Android and iOS devices like the Samsung S20 and the iPhone.
There are other multifactor applications you can use and we also like the Google Authenticator, but Microsoft will support the Microsoft Authenticator App with your Office 365 subscription. Both the Google Authenticator and Microsoft Authenticator App are free.
