This guide is intended to aid and serve as a “how to” for all users as they enroll in Multi-Factor Authentication.

What is Multi-Factor Authentication (MFA)?

Multi-Factor Authentication (MFA), is a Microsoft delivered feature which better protects enrolled users and their account by requiring additional steps when signing in. By setting up multi-factor authentication, you add an extra layer of security to your Office 365 account. The first step is to sign into, you will automatically be prompted to enroll your device.

When you sign in from outside the CSM Network, you will be prompted to verify it is YOU signing into your account.  There are two verification options, an app or a phone call. The Microsoft Authenticator App is the preferred choice for your verification method. It is an easy to use verification method that does not result in any call related charges.

Options for MFA are:

  • Microsoft Authenticator App - If using this as an option, app installation can happen during enrollment or before. The Microsoft Authenticator App is available for mobile devices on both Android and iOS. We highly recommend this option because it is the most secure and reliable method.
  • Telephone Number - May use a mobile line number or a home phone number.

Setting Up MFA

Accessing Multi-Factor Authentication Enrollment:

You will be prompted to enroll in MFA the first time you sign in from outside the CSM network. Please see ‘Example MFA enrollment’.   You will not be prompted for MFA when signing in from your office, classroom, or open computer lab.

To modify your enrollment options, please see ‘How to Change/Update Your MFA Options’.   Briefly, just sign in to, click on your picture or initials in the circle on the upper right corner, then click on My Account, Security & privacy on the left, select Additional security verification, and finally, select Update your phone numbers used for account security.

  9. The next step will be to add a second verification method. This is helpful and recommended. IMT recommends do not use the mobile number which the app is installed on. If your mobile phone is not available then both methods of verification would not be accessible. Use of a home phone number or a direct line office phone number.
