"Multi-Factor Authentication (MFA) is a security system that verifies a user’s identity by requiring multiple credentials. Rather than just asking for a username and password, MFA requires other—additional—credentials, such as a code from the user’s smartphone, the answer to a security question, a fingerprint, or facial recognition."
When you have MFA enabled you will be prompted to confirm any login attempts through the OneLogin Protect app (avail for both iOS and Android). PLEASE NOTE: MFA is only triggered when you are off campus.
Which means that while ON campus you will NOT be prompted for MFA.
Ex: You are at home, trying to login to Office 365 on your laptop. You will be prompted to confirm the login on the OneLogin Protect app as seen below.
If this is a legitimate login request, i.e. you are logging in, click Accept. But if you are NOT trying to login, then it is safe to say that this is an illegitimate request and you should deny it.
Congratulations! You just prevented unauthorized access to your account AND protected yourself and your colleagues from a potential attack!
If you would like to setup MFA please see this article: How do I sign up for Multi-Factor Authentication (MFA)?
