Setting up Two Factor Authentication (2FA) for Office 365.
Two-factor authentication (2FA) is a second layer of security to protect an account or system. Users must go through two layers of security before being granted access to an account or system.
2FA increases the safety of online accounts by requiring two types of information from the user before the user can log in. The first factor is the password; the second factor is the additional item. This means that even if someone has your password, they are unable to gain unauthorized access to your account.
We are using Google for our 2FA to Office 365, the steps to set this up are noted below.
