How to install and setup Microsoft multi-factor authentication

Before we begin, you or your IT administrator must have enabled MFA before being able to follow the steps below. Your company will be notified in advance on this happening. 

Note:
Once multi-factor authentication is enabled, you'll have 14 days to complete the following steps before they become mandatory and your Microsoft applications, like Outlook, Teams and office applications will stop working until authentication is completed. 

 

  1. Go to https://office.com
  2. Click on Sign in
  3. Type your username and click Next
  4. Type your password and click on Sign in.
    If you don’t know your password, please contact us on 0800 160 1111 and we'll provide it to you.
  5. You will now be required to provide more information and start enrolling your device against your Microsoft 365 account.

  7. Once you have downloaded the app, ensure you allow the app to use your camera, if asked. If the app can't use the camera, you will not be able to complete the setup correctly.
  8. Once the app is installed, you will need to login to the app with your work e-mail address (e.g. name@company.co.uk) and then scan the QR code on the setup page with your mobile phone.

    You are able to set a backup option: the normal MFA will be sent by text. You will be asked to enter your mobile phone number and decide if you want to have your validation done via an SMS or by having Microsoft call you.

  12. Once completed you will receive either a text with a 6 digit code or a phone call from Microsoft. Enter the code and click "Next".

    When successful, you will receive the following screen “SMS verified successfully".

You're now ready to use Microsoft Authenticator as the default sign-in method. You will need to reconnect to Outlook and Teams with your password and MFA verification only once. When logging into the browser for these applications, you will need to be verified every time.
