In this article I want to illustrate how I would notify my users of the upcoming activation of Additional Context and Number Matching in their MFA requests.
If you are looking for a guide on how to enable Additional Context and Number Matching, follow the guide linked below.
Feel free to use the message below as your own. The images are taken from the Microsoft Docs.
From [replace with activation date] forward, you will be asked to enter additional details in your MFA (Multi-factor authentication) prompts.
On your PC screen, you will be presented with a number, and you will be asked to enter this same number inside of your MFA request on your phone to complete the approval.
You will also get a map that will show the location where the request was made from. This must be taken as a general indication and it’s not always going to be your exact location, since Internet providers are not bound to route your connection from a point closest to you.
Please deny and report immediately to the IT department if you receive a request that was not done by you, or you do not recognize the location you are being shown.
