To monitor your child’s iPhone, you need to use a tracking application. The conditions to get started with an app:
- To know the iPhone’s iCloud credentials
- To enable iCloud backup
- To disable 2-factor authentication
iPhone trackers are account-based. A parent adds their kid’s iPhone credentials to the app’s Control Panel, which opens up in an online account, and starts getting updates about any activity, performed on the target device (text messages, calls, web searches, apps usage, chats in WhatsApp, GPS location, etc.).
