## FAQ
354
+
355
+
### Can I opt out of number matching?
356
+
357
+
Yes, currently you can disable number matching. We highly recommend that you enable number matching for all users in your tenant to protect yourself from MFA fatigue attacks. Microsoft will enable number matching for all tenants by Feb 28, 2023. After protection is enabled by default, users can't opt out of number matching in Microsoft Authenticator push notifications.
358
+
359
+
### What about my Apple Watch?
360
+
361
+
Apple Watch will remain unsupported for number matching. We recommend you uninstall the Microsoft Authenticator Apple Watch app because you will have to approve notifications on your phone.
362
+
363
+
### What happens if a user runs an older version of Microsoft Authenticator?
364
+
365
+
If a user is running an older version of Microsoft Authenticator that doesn't support number matching, authentication won't work if number matching is enabled. Users need to upgrade to the latest version of Microsoft Authenticator to use it for sign-in.
