Multi-Factor Authentication, also known as Two-Factor Authentication, is a way to prevent unauthorized access to your E-mail by adding additional security verification methods.
There are at least three possible ways to restrict and protect access to our services:
- Something you know (passwords)
- Something you have (authenticators)
- Something you are (biometrics)
Right now, we are only asking for something you know-- your password. Unfortunately, passwords have a tendency to be guessed or stolen.
The practical way to add additional security verification is to use what almost everybody already has-- a cell phone or tablet.
When we enforce MFA on your account, you will be asked for not only something you know (your password), but also something you have (your mobile device). But what about 'something you are'? If you are using "Face ID" or a fingerprint to unlock your phone, then you are essentially using your smartphone as a biometric scanner. You are proving that you are physically holding your device.
The Setup process only takes a few minutes and requires a mobile device like a phone, a tablet or even a laptop. If you need to read more, there is plenty of material available on Microsoft's website at aka.ms/mfatutor
