iOS 18 Face ID lock and Hidden folder · CHIA CHUN LEE · checked November 2026

Time needed
4 taps
Needs iOS 18 or later

Works for Photos Backup for Synology whether or not it has its own passcode. No download needed.

Short answer

Touch and hold Photos Backup for Synology's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Photos Backup for Synology 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 Photos Backup for Synology with Face ID

  1. Find Photos Backup for Synology on your Home Screen or in App Library.
  2. Touch and hold the icon until the quick-actions menu opens.
  3. Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
  4. Tap Require Face ID again to confirm. Photos Backup for Synology now asks for authentication every time it opens.

To test it, close Photos Backup for Synology from the App Switcher and open it again. You should see the Face ID prompt before any content appears.

Hide Photos Backup for Synology in App Library

  1. Touch and hold Photos Backup for Synology's icon and tap Require Face ID.
  2. Choose Hide and Require Face ID instead of Require Face ID.
  3. Confirm. The icon leaves your Home Screen and moves to the Hidden folder at the bottom of App Library.
  4. 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 Photos Backup for Synology?

Photos Backup for Synology is a photo backup app, the kind of app that tends to hold personal information 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 Photos Backup for Synology sends to its developer; for that, see Photos Backup for Synology's full privacy report.

What the lock does and does not do

  • Ask for Face ID, Touch ID or passcode every time Photos Backup for Synology opens

It does not

FAQ

Does Photos Backup for Synology have its own passcode?
Some apps offer an in-app PIN or biometric lock in their settings. The App Store privacy label does not say whether Photos Backup for Synology does; the iOS 18 lock works regardless.
What happens to Photos Backup for Synology's notifications when it is locked?
Locked and hidden apps do not show message previews or content in notifications, and their content does not appear in Spotlight search or Siri suggestions.
Can someone who knows my passcode open a locked app?
Yes. If Face ID fails, the lock falls back to your device passcode. Keep the passcode private if the lock matters to you.
Is a locked Photos Backup for Synology encrypted?
The lock controls who can open the app on this iPhone. It does not change how the app stores or syncs data. Encryption depends on the developer and on your device passcode.
Why can't I see the Require Face ID option?
You need iOS 18 or later. Some Apple apps such as Settings, Calculator, Maps and Camera cannot be locked or hidden.
Does hiding Photos Backup for Synology remove it from my purchase history?
No. Hidden apps still appear in App Store purchases and in Settings › Apps, and Screen Time reports still include them.
