How to set up iPhone Screen Time so it can't be disabled

Screen Time looks locked once you set a passcode. It usually is not — but the reason is not the one most guides give. One change closes it properly, and it is not the one this post originally recommended.

Updated 16 August 2026. This post originally said the Shortcuts method below was the only way to make Screen Time unbypassable, and described the weakness as Settings being reachable. Both were wrong. It was then revised to present the two methods as alternatives, which was still too generous to the Shortcuts approach: it is friction, not a lock, and it leaves the reset route completely untouched. The custodian account is the fix. See every iPhone app blocker shares the same bypass for why this applies to Brick, Opal and every other blocking app as well.

Where Screen Time actually leaks

Screen Time lets you set app limits, downtime windows, and content restrictions, all locked behind a passcode. With that passcode set, you cannot switch Screen Time off by walking into Settings — it asks for the passcode first.

The opening is the recovery route. Under Change Screen Time Passcode, a forgotten passcode can be reset by entering the Apple Account that was linked when the passcode was created. Apple documents this as the supported way back in. If that account is your own — which it is by default — then you can reset your own restrictions whenever you decide to, and the passcode is a delay rather than a lock.

It is worth being precise about what the passcode does and does not cover, because the two methods below are often described as if they did the same job. The passcode protects changes to Screen Time settings. It does not lock the Settings app: iOS provides no way to hide or block Settings through Screen Time, which is exactly why the Shortcuts workaround further down exists at all. Settings stays open; what sits behind the passcode are the restrictions themselves.

So the first question is not how to keep yourself out of Settings. It is who controls the account that can reset the passcode.

The direct fix: a custodian's Apple ID

Apple allows the Screen Time recovery account to be a different Apple Account from the one signed in on the phone. Have someone else create an Apple ID, and have them enter it — along with a passcode you never see — on your device. You keep your own Apple ID for everything else. You simply no longer hold the key to your own restrictions.

This needs no Shortcuts automation, leaves Settings usable, and does not depend on hiding anything. The full procedure, including the failure mode you should understand before doing it, is in the iPhone setup guide.

The Shortcuts method: friction, not a lock

Treat this section as optional extra friction, not as a second way of achieving the same thing. It restricts casual access to Settings, which is useful if you also want to stop yourself changing unrelated settings. It does not close the recovery route, and it can be undone by anyone who reaches the Shortcuts app. If you only do one thing, do the custodian account above.

iOS Shortcuts can run automations when a specific app is opened. You can use this to make the Settings app awkward to reach — by sending you back to the home screen every time it opens.

Here is how to set it up:

Open the Shortcuts app and go to the Automation tab.
Tap the + and choose App as the trigger.
Select Settings as the app and set the trigger to Opens.
Disable "Ask Before Running" — this is critical, otherwise a confirmation prompt appears every time.
Add the action Go to Home Screen as the only step in the shortcut.
Save the automation.

From this point on, tapping the Settings icon opens the app for a moment and then returns you to the home screen. Note what this does and does not do: the automation fires after Settings has opened, and Go to Home Screen navigates away rather than quitting the app. It makes Settings annoying to use, not impossible to reach.

Important: The Shortcuts app itself must also be restricted or hidden — otherwise the automation can simply be deleted. Use Screen Time to block or hide the Shortcuts app after setting this up. Do this last, in the right order, or you will lock yourself out of the ability to change anything.

Pair it with a third-party app to enforce app limits

With Settings blocked, you now need a way to enforce app limits that does not depend on Settings being accessible. This is where a third-party app like Screen Zen comes in.

Screen Zen (and similar apps) use Apple's Screen Time API to apply usage limits, but they manage everything through their own interface — not through the Settings app. This means once Screen Zen is configured and its own passcode is set, there is no accessible path to undo the limits.

The setup in Screen Zen is straightforward:

Install Screen Zen from the App Store.
Grant it Screen Time permissions when prompted.
Set your app limits — which apps are blocked, when, and for how long.
Set a passcode inside Screen Zen that is different from your device passcode and ideally not known to you (have someone else set it).

Because Screen Zen's configuration lives inside its own app — not in Settings — the Settings block from Step 1 does not interfere with it. And because Screen Zen itself can be hidden or restricted, there is no accessible way to undo the limits from the device.

Why this combination works

The two steps close two different loopholes:

The Settings block raises the cost of walking into Settings to disable Screen Time or change restrictions on impulse.
The third-party app provides app limits that are managed outside of Settings, so they remain enforceable even when Settings is inaccessible.

Together they remove the easy paths on the device itself. They do not, on their own, close the recovery route: if you still hold the Apple Account linked to the Screen Time passcode, deleting the automation and resetting the passcode remains possible for anyone patient enough to reach Settings once. That is why the custodian account above is the more complete answer, and why the two work best together. Beyond that, restoring the device from a computer defeats any on-device setup.

Order of operations

The sequence matters. Doing this in the wrong order can lock you out before you are finished, or leave gaps that make the whole setup bypassable.

Install and configure Screen Zen first, including its internal passcode.
Set the Screen Time passcode (if not already set) with a strong, secret code, and link the recovery account at the same prompt — ideally the custodian account described above, since this is the only convenient moment to set it.
Use Screen Time to restrict or hide the Shortcuts app.
Create the Settings automation in Shortcuts last.
Verify everything works before locking down further.

Test carefully before handing the device to someone else or having your passcode changed. A misconfigured setup can leave you with a phone that has broken limits and no way to repair them without a full restore.

Neither method is perfect, and no purely on-device setup is. The custodian account closes the reset route but leaves Settings usable; the Shortcuts method restricts Settings but can be undone by anyone who reaches the Shortcuts app or the recovery account. They close different doors, and using both closes more than either alone. Restoring the device from a computer defeats all of it, which for most people is an acceptable residual risk.
