Works for Offline Photo Vault whether or not it has its own passcode. No download needed.
Touch and hold Offline Photo Vault's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Offline Photo Vault 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 Offline Photo Vault with Face ID
- Find Offline Photo Vault 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. Offline Photo Vault now asks for authentication every time it opens.
To test it, close Offline Photo Vault from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide Offline Photo Vault in App Library
- Touch and hold Offline Photo Vault'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 Offline Photo Vault?
Offline Photo Vault is a photo vault, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. A photo vault holds the pictures you least want seen, so the questions that matter are where the files live, whether they are encrypted, and what happens if you forget the PIN or change phones.
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 Offline Photo Vault sends to its developer; for that, see Offline Photo Vault's full privacy report.
