Multi-Factor authentication (a.k.a. MFA) is a method to help better secure email accounts and Office 365 access. This additional security comes from having to Approve the sign-ins to your account using a mobile device. This way if a scammer has somehow managed to get your password, they will not be able to access your email, since they will not have your mobile device to approve the sign in.

IMPORTANT NOTE ABOUT EMAIL: Since not all Mobile phones support Multi-factor authentication, you will need to also download the Outlook App for your Mobile device to access your email on your mobile device after MFA is setup.

It is recommended that you use the Microsoft Authenticator App, which the following instructions are written for.

Download link for: Do not setup the account in the App, until you get to that point in the instructions below.

Frequently Asked Questions:

Why use the Microsoft Authenticator App?

There are two main reasons for using the Microsoft Authenticator App over simple txt messaging;

• With the Authenticator app you just have to click the Approve button when it pops-up on your mobile device, as opposed to having to wait for the txt message, and then typing in the provided numbers.
• The Authenticator app will work were ever you have a Wi-Fi connection. Some places may not have adequate cell signals and you may not get the txt message at all.

What university applications will require MFA?

• Outlook
• Teams
• OneDrive
• Office 365 applications including the Office 365 web page
• This list will be expanded as more applications are setup to use MFA

How often will I be asked to Approve my sign ins?

Each time you sign into a Office 365 service you will need to approve the sign in. For example when you sign into Outlook it will require you to approve the sign in, when you then go to sign in to Microsoft Teams it will require you to approve that sign in as well. Even though they are the same account, they are two separate sign in processes, and thus require approval.

But once you are signed in you do not have to approve again, until you sign out.

How long does the approval last?

Once you have approved the sign in to the Office 365 service, it will not require you to approve again until you need to sign in again. So when you start outlook in the morning, and sign in, it will ask you to approve that sign in. It will no longer ask to approve the session, until you close or sign out of Outlook.

Why implement MFA?

Multi-Factor authentication provides better protection to both the university and your information. Many online services have moved to MFA for enhanced security.
