When a child in your Microsoft account family uses a Windows 10 phone, you can find them on a map using Find your child.
Sign in to family on the Microsoft account website.
Select the child's Microsoft account, then select Find your child.
Under Show the location of your child's device, turn the switch On. As long as your child's device is turned on and can be found by our service, we'll show you where they are on the map.
To see their last known location, choose See previous location on map.
