What blocking an iPhone actually means

Blocking an iPhone can mean several different things depending on what you want to stop. You might want to prevent someone from using the device at all, restrict access to specific apps or websites, stop purchases, or lock down settings so changes require a password. Apple calls most of these features Screen Time on newer iPhones, and Restrictions on older ones. The method you use depends on whether you're controlling your own device, managing a child's phone, or preventing unauthorized access to a device you own.

The most common reason people block an iPhone is to prevent a child from accessing certain content, making purchases, or changing settings. A second reason is to lock yourself out of distracting apps during work or study time. A third is to prevent someone else from using a phone you own. Each situation uses a different set of controls, and they're not always obvious where to find them.

Key Takeaways

  • Screen Time lets you set time limits on apps, block content by age rating, and prevent changes to settings without a passcode.
  • You can block specific apps, websites, or entire categories like social media without deleting them from the phone.
  • Parental controls require a separate Apple ID and work across multiple devices if you set up Family Sharing.
  • To prevent someone from using your iPhone at all, use the lock screen passcode or Face ID, which is separate from Screen Time.
  • Blocking purchases requires both a Screen Time restriction and a separate App Store password setting.

Using Screen Time to block apps and set time limits

Screen Time is the main tool for blocking access on an iPhone. Open Settings, tap Screen Time, then tap Continue if you're setting it up for the first time. You'll choose whether this is your device or a child's device — this choice matters, because a child's device requires a separate parent passcode.

Once Screen Time is on, tap App Limits to set how long someone can use specific apps each day. Choose the app category (Social Networking, Games, Entertainment, and so on) or individual apps, set the time limit in hours and minutes, and choose which days it applies to. When the time runs out, the app will show a timer and then become unavailable until the next day resets. The person using the phone can request more time, which sends a notification to the parent or device owner.

To block an app entirely rather than just limit its time, go to Screen Time, tap App Limits, and set the limit to zero minutes. The app will be blocked all day. Alternatively, go to Screen Time > Content & Privacy Restrictions, turn on Content & Privacy Restrictions, tap Allowed Apps, and toggle off any app you want to hide. That app will disappear from the home screen and won't be accessible without turning the restriction back off.

Blocking websites and content by age rating

Screen Time also controls what websites and content someone can see. Go to Settings > Screen Time > Content & Privacy Restrictions and make sure it's turned on. Then tap Content Restrictions and choose Web Content. You can select Unrestricted, Limit Adult Websites, or Allowed Websites Only.

Limit Adult Websites will block known adult sites but allow most other content. Allowed Websites Only is much stricter — it blocks everything except a whitelist of sites you manually add. To add allowed sites, tap Allowed Websites Only, then tap Add a Website Under Allowed, and type in the full web address. This mode is useful for young children but will block legitimate sites you haven't pre-approved, so you'll need to add sites as the child encounters them.

You can also restrict content by age rating. In the same Content Restrictions menu, scroll down to Apps, Music, TV Shows, Books, and Movies. Choose the maximum age rating allowed — for example, if you set Apps to 12+, only apps rated for ages 12 and up will be accessible. This prevents accidental downloads of apps rated for older ages.

Preventing purchases and in-app spending

Blocking purchases requires two separate steps. First, go to Settings > Screen Time > Content & Privacy Restrictions, turn it on, and tap iTunes & App Store Purchases. Set In-App Purchases to Don't Allow. This stops anyone from spending money inside apps.

Second, go to Settings > [Your Name] > Media & Purchases > Password Settings and choose Require Password. Set it to require a password for every purchase, or choose to require it after 15 minutes of not entering one. This is separate from Screen Time and adds a second layer of protection. Without both steps, someone could still make purchases through the App Store itself.

If you're managing a child's device, make sure you know the Screen Time passcode but the child does not. If the child knows the passcode, they can turn off all these restrictions themselves. Write the passcode down somewhere safe — if you forget it, you'll need to erase the phone and set it up again to reset Screen Time.

Setting up parental controls with Family Sharing

If you have multiple children or devices, Family Sharing lets you manage Screen Time from your own iPhone instead of having to unlock each child's phone. Go to Settings > [Your Name] > Family Sharing and tap Add Family Member. You can add children or adults. For children, you'll create a child Apple ID or link an existing one.

Once Family Sharing is set up, open the Screen Time app on your own phone. You'll see a list of family members at the bottom. Tap a child's name to see their Screen Time summary and adjust their limits, blocked apps, and content restrictions from your device. Changes sync to their phone within a few minutes.

Family Sharing also controls purchases across the family. When a child tries to buy an app or make an in-app purchase, a notification goes to the parent, who can approve or decline it. This is useful because it lets children request things rather than being completely blocked, and it gives you visibility into what they're trying to access.

Locking the iPhone itself so no one can use it

Screen Time controls what someone can do on the phone, but it doesn't prevent them from using the phone at all. To actually lock someone out of the device, use the lock screen passcode or Face ID. Go to Settings > Face ID & Passcode (or Touch ID & Passcode on older phones) and tap Turn On Passcode. Choose a six-digit code, or tap Passcode Options to use a custom code or four digits.

Once a passcode is set, the phone will lock after a period of inactivity (you can set this in the same menu under Auto-Lock). Anyone trying to use the phone will need to enter the passcode or use Face ID or Touch ID. This is completely separate from Screen Time — it's the basic security feature that prevents anyone from accessing the phone at all without your permission.

If you forget the passcode, you cannot recover it. You'll need to erase the phone using Find My iPhone or by connecting it to a computer with Finder (on Mac) or iTunes (on Windows). This is why it's important to write down your passcode and store it somewhere find, separate from the phone itself.

Restricting changes to settings and accounts

Screen Time can also prevent someone from changing important settings. Go to Settings > Screen Time > Content & Privacy Restrictions and turn it on. Then tap Allowed Changes and choose what can be modified without the Screen Time passcode. You can restrict changes to Account Changes, Cellular Data, Contacts, TV Provider, and Volume Limit.

For example, if you turn off Account Changes, someone cannot add or remove email accounts, change the Apple ID, or modify iCloud settings without entering the Screen Time passcode. This is useful if you want to prevent a child from signing out of their account or adding their own Apple ID to the device. If you turn off Cellular Data, they cannot turn cellular data on or off, which prevents them from using data when you've set a limit.

These restrictions only work if the person doesn't know the Screen Time passcode. If they do, they can change any setting they want. For this reason, Screen Time is not a security feature — it's a parental control or a personal discipline tool. If you need to actually prevent someone from accessing the phone, use the lock screen passcode instead.

Frequently Asked Questions

Can someone bypass Screen Time if they know my Apple ID password?

No. Screen Time uses a separate passcode that is not the same as your Apple ID password or lock screen passcode. However, if someone knows the Screen Time passcode, they can turn off all restrictions. If you suspect someone has changed your Screen Time passcode, you'll need to erase the phone and set it up again to reset it.

What's the difference between Screen Time and the lock screen passcode?

The lock screen passcode prevents anyone from using the phone at all. Screen Time lets someone use the phone but controls what they can access. You can have both on the same phone — the lock screen passcode protects the device, and Screen Time protects specific apps and settings.

Can I block an app on my iPhone without blocking it on my iPad?

Yes, if you don't use Family Sharing. If you do use Family Sharing, Screen Time settings sync across all your personal devices. To block an app on only one device, turn off Family Sharing on that device or manage Screen Time separately on each one.

What happens if a child requests more time on a blocked app?

A notification appears on the parent's phone asking to approve or deny the request. If you approve, the child gets 15 more minutes. If you deny, the app stays blocked. The child can request again after the 15 minutes ends or the next day.

Can I block someone from deleting apps?

Yes. Go to Settings > Screen Time > Content & Privacy Restrictions, turn it on, tap Allowed Changes, and turn off Deleting Apps. This prevents anyone from removing apps from the home screen without the Screen Time passcode. The apps will still be installed but hidden from view.
