To improve security Microsoft is rolling out an added layer of authentication -- a number-matching security feature – which will be a default security feature.

Microsoft will deploy the update starting Feb. 27 across organizations globally. Those using the Microsoft Authenticator app or who want to start using the number-matching security feature need to install the latest version of the application. The Apple Watch Microsoft Authentication app does not currently support number matching.

Authentication number matching is being added to avoid accidental account access approvals and protect against Multi-Factor Authentication fatigue attacks, whereby online attackers repeatedly bombard an individual with account access requests after the hacker has gained their password. Users will see a map image with the location of the sign-in and can insert the given number and tap “Yes” to go ahead with authentication or decline the request by selecting “No, it’s not me.”

Stephen Karamatos, manager of technology and innovation in Information Technology Services, encourages members of the campus community to use the Microsoft Authenticator app as their preferred second factor method.

“This change may even be quicker for some to enter the two-digits rather than waiting for a call or message and then imputing the six digits from that message,” he says.

If you have a problem with your UWin Account after the number matching roll out, submit a ticket with the IT Service Desk.
