You've probably felt that sudden spike of anxiety when you hand your phone to a toddler or a curious friend. It’s not just about privacy. It’s the very real fear that they’ll accidentally delete your work emails, buy $400 worth of "Gems" in a mobile game, or stumble onto something they really shouldn’t see on the open internet. Honestly, knowing how to restrict a phone is basically a survival skill in 2026. We live through these slabs of glass. If you don't lock them down, you’re basically leaving your front door wide open in a crowded city.
It isn't just for parents, either.
Maybe you’re trying to cure your own doom-scrolling habit. Maybe you’re lending a device to a colleague. Whatever the "why" is, the "how" has changed a lot lately. Apple and Google have been in an arms race to add more "Digital Wellbeing" and "Screen Time" features, but they hide them behind layers of confusing menus. You have to go hunting.
The Nuclear Option: Guided Access and App Pinning
Sometimes you don't need to lock the whole phone. You just need to trap the user in one single app. This is the absolute gold standard for when you're letting a kid play a game or showing a relative a photo gallery.
On an iPhone, this is called Guided Access. You’ll find it under Settings > Accessibility. Once you toggle it on, a triple-click of the side button locks the phone into whichever app is currently open. It's genius. You can even draw circles on the screen to disable specific buttons. Want to make sure they can’t click the "Buy" button? Just draw a circle over it. They can tap all day; nothing happens.
Android has a similar feature called App Pinning. It’s a bit more buried. Usually, you have to go to Security & Privacy > More Security Settings to find it. Once it's on, you open your "Recents" view, tap the app icon, and hit "Pin." To get out, you usually have to swipe up and hold, then enter your passcode. It’s simple. It works. It prevents the dreaded "oops, I closed the app and now I'm looking at your bank account" moment.
Setting Up a Digital Perimeter with Screen Time
If you’re looking at how to restrict a phone for a child over the long term, you have to move past temporary fixes. You need a system.
Apple’s Screen Time is probably the most robust version of this. It’s not just a timer. You can set "Downtime," which basically bricks the phone (except for calls and specific apps you allow) during certain hours. But the real power is in the "Content & Privacy Restrictions." This is where you can block adult websites, stop them from installing new apps, or—more importantly—stop them from deleting apps.
I’ve seen parents lose months of photos because a kid thought the "X" on the app icon looked like a fun game. Don't be that person.
Google’s Family Link is the Android equivalent. It’s actually a separate app you download. It gives you a literal dashboard of your kid's digital life. You can see how long they spent on YouTube vs. Minecraft. You can lock the device remotely from your own phone. It’s a bit Big Brother-ish, sure, but in a world where the internet is designed to be addictive, it’s a necessary tool.
The Web is a Wild West
Let's talk about browsers. Chrome and Safari are doorways to everything. If you're trying to how to restrict a phone effectively, you have to deal with the browser.
You can’t just trust "Safe Search." It’s a filter, not a wall. On iOS, you can actually limit adult websites at the system level under Content & Privacy. On Android, you’re better off using a DNS-level filter. Services like NextDNS or CleanBrowsing are incredible for this. You change one setting in the "Private DNS" section of the phone's network settings, and suddenly, the entire device—every app, every browser—is filtered at the source. It blocks porn, gambling, and even some malware.
It’s a set-it-and-forget-it solution. Honestly, more people should use this even on their own phones just to stay productive.
Beyond the Basics: Focus Modes and App Timers
Sometimes the person you're trying to restrict is yourself. We've all been there. It's 11:00 PM, you're "just checking one thing," and suddenly it's 1:00 AM and you're watching a video about how to restore old rusty tools.
Focus Modes on iOS and Digital Wellbeing on Android are your friends here. They allow you to create "work" profiles or "sleep" profiles. On my phone, I have a "Deep Work" mode that hides every single social media app and silences all notifications except for my wife and my boss.

- You can schedule these to turn on automatically based on time or location.
- You can change your entire home screen layout so the distracting apps aren't even visible.
- Android's "Grayscale" mode is a secret weapon; it turns your screen black and white, making the colorful, dopamine-heavy world of Instagram look incredibly boring.
The Reality of "Bypassing"
Here is the truth: kids are smart. If there is a way to get around a restriction, they will find it on Reddit or TikTok within twenty minutes. They’ll change the time zone on the phone to trick the "Downtime" clock. They’ll use the "Share" button in a restricted app to open a web browser window that bypasses the main filter.
There is no such thing as a 100% restricted phone.
The goal isn't to create an unbreakable vault. It's to create enough friction that the person using the phone stays within the lanes you've set. Communication is always going to be more effective than a passcode. If you’re locking down a phone for a teenager, explain why. If you don’t, they’ll just see it as a puzzle to solve.
Actionable Steps to Lock It Down Right Now
If you want to start restricting a device today, don't try to do everything at once. Start with the most high-impact moves.
- Audit the App Store: Go into the settings and require a password for every single download, even the free ones. This stops the "hidden" apps from appearing.
- Setup Guided Access/App Pinning: This is your "emergency" tool for when you hand the phone to someone else. Get comfortable with the shortcut.
- Use a DNS Filter: This is the only way to ensure the network itself is safe, regardless of what browser is being used.
- Check the Location Sharing: Go to "Find My" or Google Maps and see who can see where that phone is. Restricting a phone isn't just about what they can see; it's about who can see them.
- Set a Screen Time Passcode: Make sure it is DIFFERENT from the phone's unlock code. This is the most common mistake people make. If the kid knows the code to get into the phone, they probably know the code to turn off the restrictions.
Restricting a device is a balancing act. You want to provide safety without making the device useless. It takes about ten minutes to set up a solid foundation, and it will save you hours of headaches later. Start with the "Content & Privacy" settings and work your way out from there.
