Where did the photo come from?
A locked iPhone won't let anyone open Photos, but several features pull pictures from your library and show them without asking for Face ID. Think back to what the screen looked like when it happened. That usually tells you which one it was.
| What the person saw | Likely source | Quick fix |
|---|---|---|
| A different photo each time the screen woke | Photo Shuffle wallpaper | Change the shuffle selection or use a single photo |
| A full-screen photo while the phone charged on its side | StandBy | Turn off StandBy, or change which photos it shows |
| Photos after swiping on the Lock Screen | Widgets allowed when locked | Turn off widget access under Allow Access When Locked |
| A photo inside a message banner | Notification preview | Stop previews showing on the Lock Screen |
The steps below match iOS 27, the version Apple's user guide covers at the time of writing.
Photo Shuffle wallpaper
Photo Shuffle rotates through a set of photos as your wallpaper. If you let it pick photos for you instead of choosing them one by one, it can land on something you'd rather keep to yourself.
- Press the side button, then touch and hold the Lock Screen until Customize appears.
- Swipe to the Lock Screen that shuffles and tap Customize.
- Tap the photo thumbnail to change the photo selection. Remove anything private, or choose photos yourself.
- While you're there, tap More (•••) to check the shuffle frequency.
If you don't want any surprises, swap Photo Shuffle for one fixed photo. You can also delete the shuffle Lock Screen entirely: open the Lock Screen gallery the same way, swipe up on it and tap the trash button.
StandBy while charging
StandBy turns a charging iPhone into a bedside clock or photo frame. On most models it starts when the phone is on the Lock Screen, on a charger and turned on its side. The Photos view is the one that catches people out, because it's meant to be seen from across the room.
- Turn StandBy off: Settings → StandBy → turn off the StandBy switch.
- Keep StandBy, drop the photos: swipe left or right in StandBy to move to a clock or widgets view instead. On iPhone Duo, the Photos face has a Select button that changes which photos appear.
- Hide alerts in StandBy: in Settings → StandBy, turn off Show Notifications.
Apple says StandBy remembers your choice for each place you charge with MagSafe, so check the charger at work as well as the one at home.
Widgets and previews you can reach while locked
Apple lets some features, including widgets, work from the Lock Screen without unlocking. That's convenient, but it also means anyone holding the phone can swipe to them.
- Go to Settings → Face ID & Passcode (or Touch ID & Passcode) and enter your passcode.
- Under Allow Access When Locked, turn off the features you don't need on a locked phone, including widgets.
Apple notes that turning off Lock Screen access to a feature stops someone who has your iPhone from using it without unlocking it.
If you placed a widget on the Lock Screen itself, edit the Lock Screen (touch and hold, then Customize), tap your existing widgets and remove the one that shows personal content.
For message previews, go to Settings → Notifications → Show Previews. When it's set to Always, Apple says the contents of notifications show on the Lock Screen without unlocking, and that includes photos someone just sent you. Pick a setting that keeps previews hidden until you unlock.
Keep the photo out of these features for good
Changing settings fixes today's leak. To stop a private photo from being picked again later, take it out of the pool these features draw from.
- Hide it. In Photos, touch and hold the photo and tap Hide. Apple says hidden items don't appear in the Library, other albums or the Photos widget on the Home Screen. With iCloud Photos on, it's hidden on your other devices too. Apple's page doesn't cover Photo Shuffle or StandBy, so recheck those after hiding.
- Stop featured picks. Memories and Featured Photos can surface the same photos. Our guide to keeping private photos out of Memories and widgets covers those settings.
- Move it out of Photos. A photo that's no longer in your library can't be chosen by any Photos feature. That's the idea behind a separate vault app such as VaultBolt, which encrypts imported photos and locks when you leave the app. VaultBolt isn't on the App Store yet; our guide to hiding photos on iPhone compares the built-in options you can use today.
If the same worry applies when you hand your phone over, read handing your iPhone to someone without them seeing private photos. For a broader review of what your phone shows while locked, use the iPhone privacy settings checklist.
What you can't undo
If someone took a photo of your screen, settings won't get that back. What you can control is what shows next time. If the image was intimate and you think it's being shared, our guide on someone screenshotting your photo explains reporting and takedown options.
Frequently asked questions
Can someone see my photos if my iPhone is locked?
They can't browse your library, but they can see whatever iOS puts on the locked screen: your wallpaper, StandBy, widgets that are allowed when locked, and notification previews. Each of these can be changed in Settings.
Do hidden photos show up in widgets?
Apple says hidden photos don't appear in your Library, other albums or the Photos widget on the Home Screen. Apple's hiding guide doesn't mention Photo Shuffle or StandBy, so check those two yourself after hiding a photo.
Does hiding a photo on my iPhone hide it on my iPad too?
Yes, if you use iCloud Photos. Apple says photos you hide on one device are hidden on your other devices too.
