iPhones have a built-in feature called “Find My” that allows users to share their real-time location with selected contacts. To set it up, go to Settings > [your name] > Find My, then enable “Share My Location.” Next, open the “Find My” app, tap on “People,” and select “Share My Location.” Enter the Apple ID email or phone number of the person you want to share with and send the request. Once accepted, both parties can see each other’s location in the Find My app. This feature uses end-to-end encryption to protect shared location data, as detailed in Apple’s security whitepapers. Always keep iOS updated to mitigate vulnerabilities like CVE-2023-42824, which impacted older versions of iOS. For more advanced location monitoring, third-party parental control apps like mSpy offer additional features—review their data privacy and encryption practices before use.
