Microsoft 365 - MultiFactor Authentication Setup


Introduction - What is Multi Factor Authentication (MFA)?

Multi-factor Authentication (MFA) is an authentication method that requires the user to provide
two or more verification factors to gain access to their online account. MFA is a core component of a strong identity and access management (IAM) policy. Rather than just asking for a username and password, MFA requires one or more additional verification factors, which decreases the likelihood of a successful cyber attack. The main benefit of MFA is it will enhance your organization's security by requiring your users to identify themselves by more than a username and password.

While important, usernames and passwords are vulnerable to brute force attacks and can be
stolen by third parties. Enforcing the use of an MFA leveraging either the Microsoft Authenticator
Application (preferred) or a phone call means increased confidence that your organization will stay safe
from cyber criminals.

This document will outline the procedure needed to successfully complete your MFA registration
using your mobile phone to ensuring account security.

Second factors for two-factor authentication methods

Allowed Factors

o Phone Factor (Phone Call)
o Token via Mobile App
o Push notification via Mobile App (Phone needs to be connected to the internet)

Disallowed Factors
o SMS Text Message
o Hardware Token
o Mail

We recommend configuring two methods for MFA. The easiest method to use is Push Notification via
the Microsoft Authenticator app found in the Google Play and Apple App Store. The app is free of charge
to download and use.
