Start by downloading the “Microsoft Authenticator” app from Google Play or the App store:
Open the app and accept the terms and conditions – you’re now ready to add your Microsoft account, which will protect your account with a 2 step verification process. Now put your smartphone aside for a while and move to the next steps.
Use your computer to log onto the Multi Factor Authentication setup page: https://aka.ms/MFASetup/
1. Log in using your email address and password
2. Click ”Next”
3. Choose ”Mobile app” in the drop-down menu, choose “Receive notifications for verifications” and click “Set up”
4. Go back to your phone. Press “SCAN QR CODE” in the Authenticator app. (iPhone: Please allow for the app to use the camera and also notifications on your device)
5. Point the camera towards the QR code on your computer screen – it will automatically be scanned, which adds your Microsoft account to the Authenticator app.
Your account has now been added – it should look like this example:
6. Click ”Next” and ”Next” again on your computer
7. You should now receive a notification on your phone, which asks you to approve the sign-in request. Press “Approve” to confirm it’s you logging on to Microsoft. (You might be asked to unlock the app using your device PIN-code, fingerprint or Face-ID)
8. In case you’ve lost your phone, and therefore don’t have access to the Authenticator app, you can enter your phone number to receive text-messages with a onetime password instead.
9. Click ”Save” on the bottom of the page, followed by ”Verify preferred option”
10. You will receive a new notification on your phone – press “Approve” to verify the MFA setup.
11. Click ”Close” and you’re all done – you’ve now enabled MFA on your Microsoft account.
