How to Lock Gallery Media File Manager on iPhone

iOS 18 Face ID lock and Hidden folder · Hetal Thummar · checked November 2026

Time needed
4 taps
Needs iOS 18 or later

Works for Gallery Media File Manager whether or not it has its own passcode. No download needed.

Short answer

Touch and hold Gallery Media File Manager's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Gallery Media File Manager 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 Gallery Media File Manager with Face ID

  1. Find Gallery Media File Manager 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. Gallery Media File Manager now asks for authentication every time it opens.

To test it, close Gallery Media File Manager from the App Switcher and open it again. You should see the Face ID prompt before any content appears.

Hide Gallery Media File Manager in App Library

  1. Touch and hold Gallery Media File Manager'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 Gallery Media File Manager?

Gallery Media File Manager 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 Gallery Media File Manager sends to its developer; for that, see Gallery Media File Manager's full privacy report.

What the lock does and does not do

It does

  • Ask for Face ID, Touch ID or passcode every time Gallery Media File Manager opens
  • Hide message previews in notifications
  • Keep Gallery Media File Manager'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 Gallery Media File Manager stores data
  • Sync to your iPad or other devices
  • Remove Gallery Media File Manager 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.

Other settings worth checking for Gallery Media File Manager

  1. Tracking

    Settings › Privacy & Security › Tracking. If “Allow Apps to Request to Track” is off, apps cannot ask, and they are told to treat you as having declined. You can also turn it off for this app alone.

  2. Photos

    Settings › Privacy & Security › Photos. Limited Access lets you pick exactly which pictures the app can see; Add Photos Only lets it save without reading your library.

  3. Notifications

    Settings › Notifications › Gallery Media File Manager › Show Previews: When Unlocked keeps message and account details off the Lock Screen.

FAQ

Does Gallery Media File Manager 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 Gallery Media File Manager does; the iOS 18 lock works regardless.
What happens to Gallery Media File Manager'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 Gallery Media File Manager 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 Gallery Media File Manager 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.
