Works for PhotosX whether or not it has its own passcode. No download needed.
Touch and hold PhotosX's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts PhotosX behind Face ID, Touch ID or your passcode; choose Hide and Require Face ID instead to move it into App Library's Hidden folder as well.
Lock PhotosX with Face ID
- Find PhotosX on your Home Screen or in App Library.
- Touch and hold the icon until the quick-actions menu opens.
- Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
- Tap Require Face ID again to confirm. PhotosX now asks for authentication every time it opens.
To test it, close PhotosX from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide PhotosX in App Library
- Touch and hold PhotosX's icon and tap Require Face ID.
- Choose Hide and Require Face ID instead of Require Face ID.
- Confirm. The icon leaves your Home Screen and moves to the Hidden folder at the bottom of App Library.
- To open it later, swipe to App Library, tap Hidden and authenticate.
Hiding also locks the app. To undo either, touch and hold the icon again and choose Don't Require Face ID.
Why lock PhotosX?
PhotosX is a private photo app, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Private-photo apps promise to keep pictures out of your main library. The label shows what leaves the phone; it cannot show whether the hiding is a real lock or just a separate folder.
Photo and video apps usually request access to your photo library. iOS lets you share only selected photos, which keeps the rest of the library — and its location metadata — away from the app.
A lock answers one question — who can open the app on this iPhone. It does not change what PhotosX sends to its developer; for that, see PhotosX's full privacy report.
What the lock does and does not do
It does
- Ask for Face ID, Touch ID or passcode every time PhotosX opens
- Hide message previews in notifications
- Keep PhotosX's content out of Spotlight and Siri suggestions
- With Hide, remove the icon from the Home Screen
It does not
- Stop someone who knows your passcode
- Encrypt or change how PhotosX stores data
- Sync to your iPad or other devices
- Remove PhotosX from purchase history or Screen Time reports
Don't see Require Face ID?
- Update to iOS 18 or later in Settings › General › Software Update.
- Make sure a passcode is set in Settings › Face ID & Passcode; the lock needs one.
- Some Apple apps (Settings, Calculator, Camera, Maps, Find My, Clock) cannot be locked or hidden.
- If your iPhone is managed by work or school, the option may be restricted.
