Information – Announcement page NHSmail introduces number matching in multifactor authentication (MFA)

19/01/2023 08:20:00 AM (GMT)

NHSmail is enabling number matching for all users of the Microsoft Authenticator app on the evening of 25 January 2023.

This is to ensure the change is managed closely, prior to the enforced change by Microsoft starting 27 February 2023.

Number matching is a key security upgrade to traditional second factor notifications in Microsoft Authenticator.

When a user responds to an MFA push notification using the Authenticator app, they will be presented with a number. They need to type that number into the app to complete the approval.

Further information is available on the NHSmail support site.
