If you have not already leveraged the rollout controls (via Azure Portal Admin UX and MSGraph APIs) to smoothly deploy number matching   for users of Microsoft Authenticator, we highly encourage you to do so. Microsoft will start enabling this critical security feature for all users of the Microsoft Authenticator app beginning February 27, 2023 and remove this feature?s rollout controls after   that date.   <\/p>\n<p>Please note that we have changed the expected behavior for NPS extension to be even more admin friendly. NPS versions 1.2.2216.1+ will be released once Microsoft starts to enable number matching for all Authenticator users. These NPS versions will automatically   prefer OTP based sign-ins over traditional push notifications with the Authenticator app. An admin can choose to disable this behavior and fallback to traditional push notifications with Approve\/Deny by setting the registry key OVERRIDE_NUMBER_MATCHING_WITH_OTP   Value = FALSE. Previous NPS extension versions will not automatically switch Authenticator push notification authentications to OTP based authentications. Please refer to the  <a href=\"https:\/\/learn.microsoft.com\/azure\/active-directory\/authentication\/how-to-mfa-number-match#nps-extension\" target=\"_blank\" rel=\"noopener\">  NPS extension section of the number match documentation<\/a> for further information.    <\/p>\n<p>[When this will happen:]  <\/p>\n<p>Beginning February 27, 2023<\/p>\n<p>[How this affects your organization:]<\/p>\n<p>To prevent accidental approvals, admins can require users to enter a number displayed on the sign-in screen when approving an MFA request in the Microsoft Authenticator app. This feature is critical to protecting against MFA fatigue attacks which are on   the rise.  <\/p>\n<p>Another way to reduce accidental approvals is to show users additional context in Authenticator notifications. Admins can now selectively choose to enable the following:  <\/p>\n<ul>\n<li>Application context: Show users which application they are signing into.  <\/li>\n<li>Geographic location context: Show users their sign-in location based on the IP address of the device they are signing into.    <\/li>\n<\/ul>\n<p><img decoding=\"async\" width=\"250\" height=\"\" alt=\"Authenticator number matching\" src=\"https:\/\/img-prod-cms-rt-microsoft-com.akamaized.net\/cms\/api\/am\/imageFileData\/RE5clZ5?ver=d861\"\"><\/p>\n<p><u>Number match behavior in different scenarios after 27-February 2023:<br \/>  <\/u><\/p>\n<ol>\n<li>Authentication flows will require users to do number match when using the Microsoft Authenticator app. If the user is using a version of the Authenticator app that doesn?t support number match, their authentication will fail. Please make sure upgrade to   the latest version of Microsoft Authenticator (App Store and Google Play Store) to use it for sign-in.  <\/li>\n<li>Self Service Password Reset (SSPR) and combined registration flows will also require number match when users are using the Microsoft Authenticator app.  <\/li>\n<li>ADFS adapter will require number matching on versions of Windows Server that support number matching.

The user must have an OTP authentication   method (e.g. Microsoft Authenticator app, software tokens etc.) registered to see this behavior. If the user doesn?t have an OTP method registered, they?ll continue to get the Approve\/Deny experience. You can create a registry key that overrides this behavior   and prompts users with Approve\/Deny. More information can be found in the number matching documentation.&nbsp;<\/li>\n<li>Apple Watch ?
