This step-by-step guide shows you how to switch your sign-in method from SMS to the Microsoft Authenticator app in just a few steps. The process takes about 5–10 minutes.

 

Important!

Please switch to Microsoft Authenticator by the end of October and then remove your SMS authentication method (see Step 7). Starting in February 2027, Microsoft will no longer support login via SMS.

 

 

What You Need to Switch:

  • Your smartphone (iPhone Smartphone running iOS 17 or later, or Android Smartphone running Android 8.0 or later)
  • A PC or laptop with Internet access
  • Your UNILU login (email address and password)

 

Step 1: Install the app

 

Download the “Microsoft Authenticator” app for free from the App Store (iPhone) or Google Play Store (Android) onto your smartphone.

 

Apple App Store: https://apps.apple.com/ch/app/microsoft-authenticator/id983156458

Google Play Store: https://play.google.com/store/apps/details?id=com.azure.authenticator

 


 

Step 2: Open the setup page

 

On your PC or laptop, open your browser and go to https://aka.ms/mfasetup, then log in with your UNILU account.


Step 3: Add a new sign-in method

 

Click “Add sign-in method” and select “Authenticator App” from the list.


Step 4: Scan the QR code


Open the Authenticator app on your smartphone, tap the QR code icon in the lower-right corner, and scan the QR code that appears on your screen.


Step 5: Confirm the number


Your screen will display a two-digit number. Enter this number in the app on your smartphone to confirm the link.


Step 6: Done!


The Microsoft Authenticator app is now set up. The next time you log in, you'll receive a verification request directly on your smartphone—easier and more secure than text messages.


Step 7: Remove the SMS method


Open aka.ms/mfasetup again, locate the “SMS” entry in your list of sign-in methods, and click “Delete.” Starting in February 2027, SMS sign-in will no longer be valid—after that, only the Authenticator will be accepted.
