Set up Screen Time for family members on iPhone
You can set up Screen Time for family members through Family Sharing—including downtime, allowances for app use, content ratings, and more. Screen Time also lets you and your family members see how they’re using their devices and use that information to structure their device use.
You can invite family members to join and enter their Apple IDs in Family Sharing on your device to begin the process. Or you can set up Screen Time for them in Family Sharing on your device. (For information on creating a child account for Family Sharing, see the Apple Support article Family Sharing and Apple ID for your child.)
Note: When you set up Screen Time for a family member through Family Sharing, both you and your family member receive notifications about their weekly report. To view the report, tap the notification.
Go to Settings > [your name] > Family Sharing > Screen Time.
Tap a family member, then tap Turn on Screen Time.
Tap Continue, then follow the onscreen instructions.
Important: If you set up Screen Time for a family member through Family Sharing and you forget the family Screen Time passcode, you can reset it on your device using your device passcode, Touch ID, or Face ID.
