How to lock your phone to one app safely

There is a specific moment that happens to all of us: you find something funny, you want to show a friend, but handing over your phone feels like a minor invasion of privacy. You don't have anything to hide, exactly, but you also don’t want them scrolling through your notifications or your camera roll.

iOS has a feature built specifically for this friction: Guided Access. It’s tucked away in your Accessibility settings, which is a bit of a misnomer since it’s really about control, but that’s where Apple puts it. Once you enable it, the workflow is surprisingly simple. You open the app you want to share—say, a video or a photo—and triple-click the side button. You’ll see a prompt to start Guided Access, and you’ll enter a PIN you set up beforehand.

From that point on, the phone is locked to that single app. Your friend can’t swipe away, open the camera, or check their texts. They are trapped in the content you wanted to show them.

There’s a layer to this that’s even more useful. You can restrict specific parts of the screen. If there’s a delete button, a share button, or a link that leads somewhere you’d rather they not go, you can literally draw over that area with your finger. The system treats that zone as untouchable. It’s a small, granular control that makes the feature feel less like a jail and more like a curated experience.

If you’re curious, go to Settings, tap Accessibility, and search for Guided Access. Turn it on, set your PIN, and you’ve got a clean, privacy-respecting way to share a moment without handing over the keys to your digital life. It’s worth trying the next time you’re tempted to just say, "You can't see that," and then handing them the phone anyway.
