What's the best way to lock an iPhone for a child?

My kid just got their first iPhone and I need it to be pretty locked down so they can’t change settings, install random apps, or stay up all night on it. I’ve poked around the built-in restrictions but I’m not sure what the safest setup is or which options actually prevent workarounds. What settings do you recommend to limit apps, web content, and screen time, and can it be managed remotely from my phone?

For a secure setup, go to Screen TimeContent & Privacy Restrictions and enable it. Set a passcode your child doesn’t know.

Key settings:

  • Apps: Use “Allowed Apps” to disable Safari, App Store, etc.
  • Content: Under “Content Restrictions,” block adult web content and set app age limits.
  • Screen Time: Create a schedule and set time limits for apps under “App Limits.”
  • Remote: Use Family Sharing on your iPhone to manage their Screen Time settings remotely from your device.

Set up Family Sharing and Screen Time with a parent passcode—you can remotely set Downtime, App Limits, block app installs/deletes/purchases, and use Content & Privacy Restrictions (whitelist sites or limit adult content) to stop common workarounds. Use Guided Access for single‑app sessions, avoid pricey MDMs, and if you want extra lightweight oversight consider Spynger.
