Children get access to adult smartphones in various ways — borrowed for a quick YouTube video, used while you’re busy, handed over as entertainment during a long journey. Without any configuration, that access is broad: your messages, your apps, your purchase history, the whole internet.
Setting up a safe, limited environment for a child using your phone doesn’t take long and prevents a range of problems you’d rather not deal with.
The Quickest Fix: Guided Access (iPhone)
iPhone’s Guided Access locks the phone into a single app with customisable restrictions. Go to Settings > Accessibility > Guided Access > Enable it. Set a passcode.
When you hand the phone to a child, open the app you want them to use (YouTube Kids, a game, whatever is appropriate). Triple-click the home button or side button. Choose “Start Guided Access.” You can disable specific areas of the touchscreen, prevent the home button from working, and disable camera and touch input.
The child is locked into that one app and cannot navigate away, access the internet, or use any other function. To exit, triple-click and enter your passcode.
This is the fastest temporary restriction available and requires no setup beyond the initial one-time configuration.
On Android: Screen Pinning
Android’s equivalent is called Screen Pinning. Enable it in Settings > Security > Screen Pinning (or Advanced > Screen Pinning on some devices).
Open the app, tap the recent apps button, find the app’s card, and tap the pin icon. The phone is now locked to that app. To exit, press and hold Back and Recents simultaneously, then enter your PIN.
YouTube Kids vs YouTube
If video content is what they need, insist on YouTube Kids rather than YouTube. YouTube Kids filters content for age-appropriateness, has a time limit feature you can set, and removes comment sections and most of the recommendation pathways that lead children from innocent content to inappropriate content via seemingly harmless steps.
On Android and iPhone, YouTube Kids is a separate download. It’s worth having installed before you need it.
Temporary Restrictions for Regular Access
If a child regularly uses your phone, set up additional restrictions in your phone’s parental controls rather than temporary pinning.
iPhone: Settings > Screen Time > Content & Privacy Restrictions. You can restrict explicit content, web browsing, purchasing, and app downloading behind a separate passcode.
Android: Settings > Digital Wellbeing > Parental Controls, or Google Family Link if the child has their own account.
The Conversation That Accompanies the Technical Controls
Technical controls have limits. An older child can find workarounds. A child who hasn’t been taught why certain content isn’t appropriate doesn’t understand why the restrictions exist.
Having age-appropriate conversations about why certain content is restricted, what to do if something makes them uncomfortable, and how to come to you if they see something upsetting is as important as any technical control. The controls are the safety net; the conversation is the education.
What the Controls Don’t Cover
No content filter is comprehensive. Something inappropriate will eventually get through. A messaging app can be used in ways you didn’t anticipate. A friend can share something on their own device that your restrictions can’t intercept.
The goal of phone restrictions for children isn’t perfect information control — that’s impossible. It’s reducing exposure to the most obviously harmful content and creating a framework where problems are brought to you rather than hidden.
