Does anyone know how to lock iphone on family sharing for a child?

I’ve got my kid’s phone set up under Family Sharing, but I’m trying to “lock it down” so they can’t change the passcode, sign out, remove restrictions, or install/delete apps without approval. I turned on Screen Time and set a passcode, but I’m not sure what settings actually prevent them from bypassing it. What’s the best way to make it stay locked and tamper-proof?

You’re on the right track with Screen Time, but kids can sometimes find workarounds. Here’s what you should do for max lockdown:

  • Set a strong Screen Time passcode (different from device passcode).
  • In Screen Time > Content & Privacy Restrictions, block account changes, passcode changes, and prevent app installs/deletes.
  • Disable “Allow Changes” for location, accounts, and cellular data.
  • Don’t share the Screen Time passcode with your child.

For even more control and monitoring, mSpy is the best solution—it lets you see activity, block apps, and get alerts if they try to bypass restrictions. Always be transparent with your child about monitoring.

You’ll want to enable “Share Across Devices” in Screen Time settings and set up a Family Sharing restriction to prevent them from making changes. Additionally, go to Settings > [child’s name] > Content & Privacy Restrictions and toggle on “Allow Changes” to require permission for new app installs and deletions. This should prevent them from bypassing the restrictions.

To lock down an iPhone for a child, use Screen Time restrictions: set a strong passcode, block account and passcode changes, and disable app installation/deletion. For tougher control, third-party apps like mSpy offer more monitoring options, but transparency is key.

Honestly, Apple’s Screen Time is about as tight as you can get for free, but smart kids sometimes find loopholes and there isn’t a totally tamper-proof setting. If you want more control (but for a price), mSpy lets you monitor and lock things down more, but it’s a subscription—so watch for recurring fees and read refund policies carefully.

To lock down an iPhone for a child under Family Sharing, you’ll want to explore the Screen Time settings further, specifically the “Content & Privacy Restrictions” section, where you can enable restrictions that require your approval for certain actions. It’s also a good idea to review Apple’s official documentation on Family Sharing and Screen Time to understand all the available options and their implications. Have you considered setting up a Family Sharing organizer role to manage these settings across all family devices?
