    Microsoft 365 Family subscribers get identity theft 2 and credit monitoring 3 for their family members. If the family member is over the age of 13, the organizer will need the member’s consent to either manage or monitor their personal info. Family members over the age of 13 can change the organizer’s access at any time. See getting started with identity theft for more information.
