No they don’t. I run an M365/Azure shop and not a single user out of hundreds has given their mobile number to Microsoft.
My personal consumer MSFT/Xbox account also has no mobile number attached.
- kevin_thibedeau 4y agoYes they do when your M365 using employer insists that you have to use the authenticator app on your personal phone and won't provide an alternative option.
- tatersolid 4y agoAt no point during setup does Microsoft Authenticator app collect your mobile number. That is in fact the whole point of the app: SMS is insecure for 2FA so collecting a mobile number makes no sense. Most of our people including myself choose to enroll a personal phone rather than carry two devices, and somehow none of these hundreds of people ever provided their mobile numbers to Microsoft. I think you are mis-remembering the setup experience, or your employer chose to enable some non-default options that uses SMS as a backup option to the app.
- kevin_thibedeau 4y agoPrior to Android 11 no permission was required to retrieve a phone number via the API.
- goatsi 4y agoDo you have evidence from the apk that phone numbers were being retrieved?
