Works for Photo Scan Plus whether or not it has its own passcode. No download needed.
Touch and hold Photo Scan Plus' icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Photo Scan Plus 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 Photo Scan Plus with Face ID
- Find Photo Scan Plus 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. Photo Scan Plus now asks for authentication every time it opens.
To test it, close Photo Scan Plus from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide Photo Scan Plus in App Library
- Touch and hold Photo Scan Plus' 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 Photo Scan Plus?
Photo Scan Plus' privacy label lists user content — the kind of data you would not want on screen if someone borrows your unlocked phone. Photo backup apps upload your library by design, including location metadata embedded in each picture.
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 Photo Scan Plus sends to its developer; for that, see Photo Scan Plus' full privacy report.
