Works for TagCam whether or not it has its own passcode. No download needed.
Touch and hold TagCam's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts TagCam 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 TagCam with Face ID
- Find TagCam 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. TagCam now asks for authentication every time it opens.
To test it, close TagCam from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide TagCam in App Library
- Touch and hold TagCam'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 TagCam?
TagCam is a photo manager, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Photo managers usually ask for full library access. That gives them every picture, along with its location and date metadata.
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 TagCam sends to its developer; for that, see TagCam's full privacy report.
What the lock does and does not do
It does
- Ask for Face ID, Touch ID or passcode every time TagCam opens

- Remove TagCam from purchase history or Screen Time reports
