Works for Web Messenger whether or not it has its own passcode. No download needed.
Touch and hold Web Messenger's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Web Messenger 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 Web Messenger with Face ID
- Find Web Messenger 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. Web Messenger now asks for authentication every time it opens.
To test it, close Web Messenger from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide Web Messenger in App Library
- Touch and hold Web Messenger'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 Web Messenger?
Web Messenger's privacy label lists location — the kind of data you would not want on screen if someone borrows your unlocked phone. Messengers see who you talk to as well as what you say. Even with end-to-end encrypted content, contact lists and metadata can be collected and linked to you.
Social apps are built around identity and contacts, so data linked to you is nearly universal. Tracking and contact upload are the settings worth checking.
A lock answers one question — who can open the app on this iPhone. It does not change what Web Messenger sends to its developer; for that, see Web Messenger's full privacy report.
What the lock does and does not do
It does
- Ask for Face ID, Touch ID or passcode every time Web Messenger opens
- Hide message previews in notifications
- Keep Web Messenger'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 Web Messenger stores data
- Sync to your iPad or other devices
- Remove Web Messenger 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 Web Messenger
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.
Location
Settings › Privacy & Security › Location Services › Web Messenger. Choose While Using or Never, and switch off Precise Location if a city-level answer is enough.
Contacts
Settings › Privacy & Security › Contacts. Limited Access shares only the people you select instead of your whole address book.
Microphone & camera
Settings › Privacy & Security › Microphone and Camera. The orange and green dots in the status bar show when either is in use.
Notifications
Settings › Notifications › Web Messenger › Show Previews: When Unlocked keeps message and account details off the Lock Screen.
