If your administrator has turned on multi-factor authentication (MFA) for your Microsoft 365 product here is the list of steps to follow to setup your MFA from a user perspective, this is typically a one time setup process:

This guide is base on using the Microsoft authenticator app, if you prefer SMS only see here for the instructions:

You will need to have your mobile phone with you when you start this process.

1. logon to Microsoft 365 webmail via using your existing account username and password.

  • Note that even if you don't normally use webmail to check your email I recommend doing this via webmail and to do it immediately as this gives you the opportunity to set it up 'on demand' rather than being eventually forced to do so (at possibly the most inopportune time)
  • I also recommend doing this from a PC rather than a mobile device, its cumbersome to do it on a mobile web browser while also trying to deal with app settings, notifications and task switching. Also impossible to scan the QR code on the phone screen from the phone itself if your taking that option.

2. After you successfully log on, a pop-up will appear asking for more information. Click next.

3. Chose the mobile app method
4. Check the 'receive notifications' option button
5. Click setup

MFA 0001

6. Instal the mobile phone app from here if necessary
7. If you have the app installed already you may already have services listed

8. Tap on the elipsis
9. Tap on add account

MFA 0006

10. Select 'Work or school account'

MFA 0007

11. Tap scan QR code

MFA 0008

11. Scan the QR code that shows on the PC screen

MFA 0000

12. The new account should now show in the authenticator app.

MFA 0009

13. This completes the setup of the authertication app.
14. Your microsoft logon will now ask for authentication, tap approve.

MFA 0010

15. The next step is to add your mobile phone number in case you don't have access to the authenticator app.
16. Chose your country, add your mobile number and click next

MFA 0003

17. Typicly you can ignore the app password, just click done

MFA 0004

18 That should be the final step. You will only need the multi factor authentication when you setup a new device or periodically when the administrator requires a re-verification.

Note that you can go to to manage your settings including and addition phone if for example you would like you office admin to be able to authenticate you if you lose your phone:
