Since no one wants to be like Cisco or Microsoft and have criminals breach their network using a technique known as MFA spamming, we are rolling out an enhanced version of MFA before the Microsoft February 27th deadline. 

The updated Microsoft Authenticator will prompt you to enter a number displayed on the sign-in screen when approving an MFA request. This new experience protects you from the accidental approvals that make MFA spamming attacks work. 

You will also notice location and application information displayed that can help determine if the MFA request was initiated by you. Below is an example of the new experience.

Please contact your vCIO if you have questions.
