How to set up parental controls on an iPhone: the full walkthrough for your child's phone

Short version: add your child to Family Sharing, open Settings, Screen Time, and set a Screen Time passcode that isn't the one they use to unlock the phone. From there you set app limits, age ratings and quiet hours. It's free and it's already on the device. Below, the whole thing done properly, including the part where it leaks.

Let's do this properly instead of halfway. Most guides walk you through the menus, tell you you're covered and send you on your way. You're not entirely covered, and I'd rather say so now than after you've stopped checking. So: first we set up Apple's parental controls the way they actually hold. Then I'll show you where a determined kid slips through, and what you can put on top so that particular gap closes.

No judgement, no rush. Fifteen minutes of setup buys back a lot of arguments. Let's go.

How to set up parental controls on an iPhone, step by step

Apple's parental controls live under Screen Time and they cost nothing. You can run them from your child's phone or from your own, and Family Sharing is what lets you do it without holding theirs. These are the steps, in order.

  1. Set up Family Sharing. Open Settings, tap your name at the top, then Family. Add your child's account, or create a child Apple Account for them right there. This links their device to yours so you can change their settings remotely. If your child is still signed in with your Apple Account, this is the moment to give them their own.
  2. Open Screen Time. Settings, then Screen Time. With Family Sharing on, your children appear under Family; tap the one you want to manage. You'll see usage reports broken down by app and by day. That alone tells you more than a week of guessing where the evening went.
  3. Set a Screen Time passcode, and make it a different one. This is the step nobody explains properly and the one that decides everything else. Under Lock Screen Time Settings, iOS asks you for a four-digit passcode. Do not use the code they type to unlock the phone. If your child knows that code, and they usually do, they can walk into Settings and undo the whole thing in about two taps. Pick something they don't know. Don't leave it written down somewhere obvious.
  4. Turn on Content & Privacy Restrictions. Inside Screen Time, open Content & Privacy Restrictions and switch it on. This is where the real decisions sit: whether they can install or delete apps, whether they can buy anything, what they can watch, listen to and browse by age rating, and what the phone is allowed to share. Give web content and in-app purchases an extra minute each. That's where the surprises come from.
  5. Add App Limits and Downtime. Still in Screen Time. App Limits puts a daily cap on a category (social, games, whatever is eating the afternoon) or on a single app. Downtime schedules the hours when the phone goes quiet for everything you haven't waved through: overnight, homework, dinner. Calls and anything under Always Allowed keep working. While you're in there, Communication Limits decides who they can reach during allowed time and during downtime.

That gives you a free, built-in and genuinely useful setup. Apple keeps the current screens documented in case a menu gets renamed in a future update: Use parental controls on your child's iPhone or iPad.

Go and set this up today, unhurried. When it's done, come back for the next section: there's a part Screen Time doesn't cover, and you want to know about it before you trust it completely.

Can a child get around iPhone parental controls?

Yes. That's the part the tutorials leave out. Not to alarm you, just so you don't lean on it harder than it can take. Screen Time is software, and software that lives inside the phone you're trying to limit always leaves a seam somewhere. Three of them get used more than the rest.

The restart trick. Restart the iPhone, open the app that has hit its limit, and keep tapping "One more minute" each time the reminder shows up. Done patiently, the cap stops meaning anything. It isn't hacking. It's a fourteen-year-old with an evening free.

Moving the clock. Anything on a schedule, Downtime most of all, depends on what the phone thinks the time is. Change the date and time in Settings and some of those rules get confused. An old classic, and the reason Downtime alone is a soft rule.

Knowing your passcode. This is the big one. If your child knows the Screen Time passcode, they open Settings and switch the lot off. And plenty of them know it, because plenty of parents reuse the unlock code. That's why step three matters more than the four steps around it. With those four digits, anyone can dismantle every restriction in the house. The whole system comes down to a number standing between your child and TikTok, and a number gets guessed, watched over a shoulder, or negotiated for every night.

None of that makes Screen Time useless. It's excellent at reports, at age-appropriate content, at setting the frame everyone agrees on. It just has a ceiling as a hard barrier, and you should know where the ceiling is. If yours has already got past it more than once, that's a whole article of its own: what to do when your child gets around every parental control you set.

What Apple's parental controls cover, and what they don't

Side by side, here's what Screen Time does well and where it runs out of road.

What you need Apple parental controls (Screen Time) Where it stops
See how much they use the phone, and on what Yes, per app and per day Nothing. It's good at this
Filter content by age (web, apps, purchases) Yes Nothing. It's good at this too
Cap the hours on one app Yes, with App Limits The cap gives way to "One more minute" after a restart
Keep an app genuinely closed Partly Falls over on a restart, a clock change or a known passcode
A limit that doesn't rest on a code No All of it hangs on four digits somebody can find out
Something that holds when they know what they're doing No This is where a physical layer earns its place

So the summary is simple. Apple gives you a very good dashboard: what's happening, what's age-appropriate, what the ordinary weekday looks like. What it doesn't give you is something that holds once your child starts testing it. That's usually the part you came here for.

The layer a restart doesn't touch

If an app is going to stay closed, the key has to sit outside the phone.

That's the whole difference. Anything that lives inside the handset can be undone from inside the handset. A code gets guessed. A clock gets moved. A restart opens a seam. The fix can't live inside the problem.

That's what Monk is. A physical tag about the size of an AirTag, NFC, no battery, nothing to charge. You choose which apps it closes. To open one of them again, you pick up the iPhone, walk to wherever the Monk is, and tap it. Every time. There's no passcode to work out and no toggle in Settings to undo. If the Monk stays in the kitchen while homework happens, the decision has already been made and nobody has to make it again at nine o'clock.

One thing worth being clear about: Monk is not more parental control. It doesn't monitor, it doesn't report back, it doesn't read anyone's messages. And you don't run it on them — they run it themselves, the same way you'd run it on your own phone. That's a different arrangement entirely from a code you hold over somebody.

And the honest limits, because we'd rather undersell. Nothing on iOS locks a phone shut completely, not Apple's tools and not ours. Someone determined enough will eventually find a way round something. What Monk takes away is the automatic reach — opening Instagram before you've decided to. Calls and the camera always work, and the app keeps three emergency unlocks for real emergencies. The promise isn't an impenetrable phone. It's that the app you closed stays closed until somebody walks back to the tag.

What Monk is, and how to bring it into the house

Monk is a physical device, designed in Spain, that puts something solid between a phone and the apps eating the evening. It works on iPhone only, iOS 16.2 and up. There is no Android version and it does not work on iPad, and we'd rather tell you that before you buy anything. It's a one-off purchase, no subscription, and the app is included.

Here's the part that surprises people: the plan doesn't start with your child's phone. It starts with yours.

  1. Use it yourself first. Tap your own phone against it one afternoon, in front of them, and say nothing about it. Children don't copy instructions. They copy what they see. That's the setting no menu in iOS offers you.
  2. Let them try it. One dinner with everyone's phones tapped out. One homework session with the usual apps closed. No speech attached — just a gesture, and then back to the potatoes.
  3. Let it become theirs. They tap it to study. They tap it to sleep. Once the gesture belongs to them, hunting for the back door stops being the interesting game. The rule is held by an object instead of by an argument every night.

If what worries you most is doing this without reading their messages or tracking where they are, start here instead: phone rules at home without spy apps. And if you're still deciding when to hand over a phone at all, we've written about what age a child should get a phone.

Common questions

Are iPhone parental controls free?

Yes. Screen Time comes with iOS at no cost and there's nothing to download. You turn it on in Settings, Screen Time, and Family Sharing lets you manage your child's device from your own iPhone. It's genuinely good for usage reports, age ratings and scheduled quiet hours. The one caveat is that as a hard barrier it can be got around.

How do I stop my child turning off parental controls?

It comes down to the passcode. Use a Screen Time passcode that isn't the code they use to unlock the phone, and don't leave it written where they'll find it. Even then, restarts and clock changes leave seams. If you want a limit that doesn't rest on a number at all, that's what a physical layer like Monk is for: the closed app opens by tapping the tag, not by typing anything.

Can Screen Time be bypassed?

It can. The three usual routes are the restart plus "One more minute" trick, changing the system clock to confuse scheduled limits, and simply switching everything off if they know the passcode. Worth knowing, not worth panicking about — it just means a lock that lives inside the phone shouldn't be the only thing you're relying on.

Do I need Monk if Screen Time is already set up?

They do different jobs. Keep Screen Time for what it's excellent at: reports, age-appropriate content, privacy settings, the shape of the week. Monk covers the part Screen Time can't — keeping a chosen app closed when the phone gets restarted, when the clock gets moved, when the code is common knowledge. One informs and filters. The other adds friction you have to get up and walk through.

You set the rule. Monk holds it

Set up Apple's parental controls this week, calmly. They're free, they're useful and they show you where the hours really go. Then, for the part four digits can't hold, put in something nobody has to renegotiate at bedtime.
