Log in to Microsoft 365 Multi-Factor Authentication !
Trouble logging into your account ?
Microsoft is changing its policy
Multi-factor authentication required
for your Microsoft 365 account?
Microsoft has recently chosen to strengthen their security, as well as that of these users. They had already implemented multi-factor authentication in office 365 for some time, but until today, it was not mandatory for companies to protect their accounts. From December 31, 2022, Microsoft intends to switch all of their O365 accounts to double authentication also called « multi-factor authentication » (MFA)
You may have some problems connecting to your emails when trying to access them from Outlook, or even your smartphone from its « mail » app! If so, you’ve come to the right place! Learn how to sign in to Microsoft’s « Authenticator » app and secure your account!
By trying to connect to your account via your web browser or other, you must have noticed that it asks you to protect your account with their new application, and asks you for that, a whole lot of manipulation to do. It then provides you with a qr code, which will be useful for your connection

» Se connecter à l’authentification multi-facteurs de Microsoft 365 ! «

Click « Next »
5. Once you get to this setup page for additional security verification, you will see in « Step 1 » two drop-down lists of choices to allow Microsoft to contact you to verify your identity.
It is highly possible that once you click « Next » (Step 4), Microsoft does not show you this additional verification window but only the « Configure Mobile App » window (Step 8)
- Select as the first choice:
» Mobile app «
7. Then choose the option:
« Receive notifications for verification »
And then click « Configure »

(In case an error has occurred, and you will have returned to the home page of the application, click on the « + » at the top right to add an account)
(Choose « Work or school account »)
(To then choose « Scan QR Code »)
12. Place the QR code inside the square in your camera
13. Your account is now visible in the « authenticator » list,
14. Once your account appears, return to the internet via your computer, on the page previously opened (opposite ←)
and click « Next »
If you did not have the additional verification window (as said above and below ↓)
and you just had to scan the QR code, then click « Next » (above↑),
You will see that your application asks you to confirm your connection.
Confirm the request, and see that your computer will have validated your double authentication.

16. Step 2 is verification in « sync » with your mobile. Go to the « Authenticator » app

(For example: Belgium) and enter your telephone number.

The code entered is a unique 6-digit code that automatically changes every 30 seconds
(which serves as a second way to validate its identity)
