How to Enable Office 365 Multi-Factor Authentication?

Are you looking for a way to set up or enable Microsoft MFA (Multi-Factor Authenticator) App on your device? Whether it’s iPhone or Android or any device. We have described all the steps to do it properly. Let’s discuss all the scenarios.

The second layer of protection called two-factor authentication (2FA) is used to confirm that the person attempting to access an account is indeed who they claim to be.

In addition to being “something you know,” a password might also be something someone else learns or comes across. Anyone who knows your login and password would be able to access and utilise your Office 365 mailbox identity without 2FA or MFA enabled.

You need your password in addition to “something you have” (such a secure token or keycard) or “something you are” (such as your identity) to confirm your identity in order to access a resource that supports two-factor authentication (2FA) (such as your fingerprint, iris or your voice).

What is Microsoft Multi-Factor Authentication?

Azure Multi-Factor Authentication (MFA) keeps things simple for users while securing access to data and apps. It gives robust authentication using a variety of simple authentication techniques and adds security by requiring a second form of identification.

If you have 2FA enabled on your Office 365 mailbox, somebody could not access your mail by simply knowing your login and password (inadvertently or on purpose).

The instructions below install a 6-digit random number generator—a “thing you have”—that is updated every 30 seconds on your mobile device. Then, in addition to your login and password, access to your 2FA-enabled Office 365 mailbox would also require this often-changing 6-digit number.
