Frequently Asked Questions

What is number matching and how do I use it?

Number matching prevents accidental approval by requiring the user to type in a two-digit code from the login screen to their Authenticator app. Number matching will also provide additional contextual information, which includes the application accessed and a map location from which the sign-in attempt originated. 

  • Your login screen will display a two-digit code
  • Enter the number into the app.
  • Press Yes to complete the approval.

Why is Microsoft switching to number matching?

Microsoft is seeing an increase in the use of a specific tactic known as MFA fatigue attacks. The goal of an MFA fatigue attack is to send endless MFA push notifications in hopes to fatigue the user into approving the sign-in request accidentally or knowingly to stop notifications.  Number matching is considered a more secure login method that reduces MFA fatigue attacks.

How will number matching look?

The Microsoft Authenticator App shown here will display information about the application and ask you to enter a two-digit number. The login page will now give you a number when logging in. After you enter the number, the login process will continue.

Will this number matching change affect notifications to my Apple Watch?

Yes, the Microsoft Authenticator Apple Watch app will not work with Number Matching. Microsoft recommends you uninstall the Microsoft Authenticator Apple Watch app.

I'm not receiving the verification code sent to my mobile device.

Not receiving your verification code is a common problem. The problem is typically related to your mobile device and its settings. Here are some suggestions that you can try:

  • Restart your mobile device.
  • Verify that your security information is correct, especially your phone number. - To make sure your information is correct, see the instructions in the Manage your two-factor verification method settings article.
  • Verify that your notifications are turned on.
