How to Lock Amtelco Secure Messages on iPhone

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

Time needed
4 taps
Needs iOS 18 or later

Works for Amtelco Secure Messages whether or not it has its own passcode. No download needed.

Short answer

Touch and hold Amtelco Secure Messages' icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Amtelco Secure Messages 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 Amtelco Secure Messages with Face ID

  1. Find Amtelco Secure Messages 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. Amtelco Secure Messages now asks for authentication every time it opens.

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

Hide Amtelco Secure Messages in App Library

  1. Touch and hold Amtelco Secure Messages' 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 Amtelco Secure Messages?

Amtelco Secure Messages 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.

Medical apps may hold the most sensitive data on your phone. Whether US health-privacy law applies depends on who runs the app, not on the App Store category.

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

What the lock does and does not do

It does

  • Ask for Face ID, Touch ID or passcode every time Amtelco Secure Messages opens

Don't see Require Face ID?

  • 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.

FAQ

Does Amtelco Secure Messages 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 Amtelco Secure Messages does; the iOS 18 lock works regardless.
What happens to Amtelco Secure Messages' 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 Amtelco Secure Messages 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 Amtelco Secure Messages 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.
