4 taps
Needs iOS 18 or later

Works for BUNKR Secure Messaging & Vault whether or not it has its own passcode. No download needed.

Short answer

Touch and hold BUNKR Secure Messaging & Vault's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts BUNKR Secure Messaging & Vault 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 BUNKR Secure Messaging & Vault with Face ID

  1. Find BUNKR Secure Messaging & Vault 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. BUNKR Secure Messaging & Vault now asks for authentication every time it opens.

To test it, close BUNKR Secure Messaging & Vault from the App Switcher and open it again. You should see the Face ID prompt before any content appears.

Hide BUNKR Secure Messaging & Vault in App Library

  1. Touch and hold BUNKR Secure Messaging & Vault'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 BUNKR Secure Messaging & Vault?

BUNKR Secure Messaging & Vault is a secure messenger, the kind of app that tends to hold personal information 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.

Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.

A lock answers one question — who can open the app on this iPhone. It does not change what BUNKR Secure Messaging & Vault sends to its developer; for that, see BUNKR Secure Messaging & Vault's full privacy report.

FAQ

Does BUNKR Secure Messaging & Vault 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 BUNKR Secure Messaging & Vault does; the iOS 18 lock works regardless.
What happens to BUNKR Secure Messaging & Vault'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 BUNKR Secure Messaging & Vault 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 BUNKR Secure Messaging & Vault 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.
