If You Use Microsoft Authenticator, Be Aware Of These Changes

What is the Microsoft Authenticator?
The Microsoft Authenticator app helps you sign into your accounts when you're using two-step verification. Two-step verification helps you to use your accounts more securely because passwords can be forgotten, stolen, or compromised.


If you are currently using the Microsoft Authenticator for multi-factor authentication, you may notice a change beginning on Monday, May 8th. This change will impact the method used to approve MFA challenges, and will affect the following:

  • Applications that don't support "number matching" (e.g., Authenticator for Apple Watch), will no longer be able to approve your authentication.
  • The Microsoft Authenticator application will no longer send an Approve/Deny "push", but, instead, will send a "number matching" challenge.

Currently, the Microsoft Authenticator smartphone application may send you a push notification that requires only an "Approve" (or "Deny") button click. Starting May 8, when you need to authenticate with Multi-Factor Authentication, the app will send you a "number matching" challenge. The application or website you are trying to access will provide you with a number—typically 2 numerical digits—and your smartphone application will ask you to input that number on your phone.

Once you input the number and click "Yes", your authentication will be complete.


Please reach out to our team if you have any questions on these changes.
