How to lend your iPhone without exposing your photos

An unlocked iPhone gives whoever holds it access to almost everything: the Photos library, messages, email, banking apps that only ask for Face ID when they open, and the Files app. Most people who borrow a phone have no bad intentions — a child swiping too far, a friend scrolling to find the photo you mentioned, a shop assistant checking a setting — but one accidental swipe is enough to land on a screenshot of a bank transfer or a scan of your ID.

The goal is not to distrust people. It is to make the phone do only what you lent it for.

Guided Access is built into iOS and is the single most useful setting for lending a phone. Set it up once:

1. 1Open Settings, then Accessibility, then Guided Access, and turn it on.
2. 2Tap Passcode Settings, then Set Guided Access Passcode, and choose a code. You can also turn on Face ID to end a session.
3. 3Optionally set a Time Limit alert so you know when the session should end.

To use it, open the app you want to lend — Phone, a game, YouTube, Maps — and triple-click the side button (or the Home button on older iPhones). Tap Start. The phone now stays inside that app: the Home gesture, Control Center and notifications banners are blocked until someone enters the Guided Access passcode or uses your Face ID.

To finish, triple-click the side button again, enter the passcode and tap End. If triple-click is already used by another accessibility shortcut, iOS asks you to choose Guided Access from a short menu.

If you have to hand over the phone without Guided Access — to show a set of holiday photos, for example — make sure the sensitive ones are not in the main Library:

1. 1Move them to the Hidden album (select the photos, tap the More button, then Hide).
2. 2Open Settings, then Apps, then Photos (Settings → Photos on iOS 16 and 17), and turn on Use Face ID or Use Touch ID. The Hidden and Recently Deleted albums now ask for your face or fingerprint.
3. 3On the same screen you can turn off Show Hidden Album so it does not appear in the album list at all.

The guide to hiding photos on iPhone walks through these steps in more detail, including the limits of the Hidden album.

For a child who borrows your phone regularly, Screen Time is another layer:

• Settings → Screen Time → App Limits lets you put a one-minute daily limit on Photos, Messages or Files. When the limit is reached the app needs the Screen Time passcode to open again.
• Use a Screen Time passcode that is different from your iPhone passcode, otherwise anyone who knows the phone code can lift the limit.
• On recent iOS versions you can also require Face ID for an individual app by long-pressing its icon and choosing Require Face ID. The guide to locking apps on iPhone compares these options.

A short routine takes less than a minute and covers most accidents:

• Close the apps you were just using, especially Photos, Messages and your banking app, so the borrower does not land in the middle of them.
• Turn on Do Not Disturb or a Focus mode, so private notifications do not appear on screen while someone else holds it.
• Check Settings → Privacy & Security → Photos to see which apps have Full Access to your library. Switching unneeded apps to Limited Access or None means a borrowed game or editing app cannot browse your photos.
• If a shop needs the phone for a while, read what to do before sending your iPhone for repair instead — a longer handover needs more preparation.

Often, yes. If someone only needs to see one picture, a document or a map, send it through AirDrop or a chat app, or show it in full screen and keep the phone in your own hand. You decide exactly what leaves the phone, and nobody needs to swipe through your library to find it.

The built-in tools rely on the phone passcode at some point: anyone who knows it can open the Hidden album or remove an app limit, and can end Guided Access too if you gave it the same code. If a few photos, videos or documents need to stay private even from people who know your phone code, a separate vault closes that gap.

• Lockboxy has its own passcode, separate from your iPhone passcode.
• Content is encrypted with AES-256 on the device before it is stored. There is no account and no server holding your files.
• The vault locks when you leave the app, and it hides its content from screenshots and the app switcher, so a borrower who opens the app switcher does not see a preview.
• The free plan holds up to 30 photos or videos and 10 files, with the full security core included.

The honest trade-off: because the key comes from your passcode, forgetting it means nobody can open the vault — not you and not us — unless you set up a Recovery Key (Premium) in advance. More answers are in the Lockboxy FAQ.
