Share location with family by choice
Built-in family sharing can help trusted people locate a device when everyone understands the arrangement and the platform supports it.
What to do
First, check
Confirm who is sharing which device and whether consent is current.
Then
Use Apple Family Sharing or Google Family Link / Location Sharing rather than a covert tracker.
If it’s not that simple
Person sharing and device finding are distinct
Sharing your location
Explain who receives the chosen sharing signal.
Helping find a device
Use an authorised family-device feature or let the owner sign in.
Membership alone
A family-group membership is not a universal live-location permission.
Good to know
Sharing a person's location and finding their missing device are related but separate settings.
