How to Lock Voice Memos on iPhone: Face ID and PIN Options

You can lock the Voice Memos app on iOS 18 or later: touch and hold its Home Screen icon, choose Require Face ID (or Touch ID or Passcode), and confirm. This protects opening the app; it does not assign a different password to each recording.

For a separate recording PIN, consider a dedicated audio vault. Do not move audio into Notes expecting to lock it: Apple does not support locking notes with audio attachments.

Lock the Voice Memos app with Face ID

1. Find Voice Memos on your Home Screen.
2. Touch and hold its icon to open the app menu.
3. Choose Require Face ID, Require Touch ID, or Require Passcode, then confirm and authenticate.
4. Close the app and reopen it to check the authentication prompt.

This uses Apple's system app-lock feature. If the option is missing, check your iOS version and Family Sharing restrictions. Locking applies only on this device; review your other devices separately.

App lock or a separate PIN: which do you need?

• Occasionally handing over your phone: start with the built-in app lock.
• A different secret from your device passcode: choose a vault that supports a separate PIN. The iOS app lock is not a new password for your audio files.
• Keeping audio off cloud services: review sync and export destinations as well as the lock. These solve different problems.

Why the locked Notes method does not work

A previous version of this guide recommended putting recordings in a locked note. That was incorrect. Apple's Notes documentation excludes audio attachments from notes that can be locked. Sharing a memo to Notes does not password-protect it.

Move a recording into an audio vault carefully

1. Start with a short, non-sensitive sample recording.
2. In Voice Memos, select it and use More > Share. Apple documents sharing a recording or saving it to Files.
3. Follow the chosen vault's import instructions. Check its supported formats and set its own PIN if available.
4. Play the imported recording, close the vault, and check that reopening requires authentication. Try exporting the sample too.
5. Only after verifying the copy and your backup plan, decide whether to remove the original. Importing does not itself remove copies in Voice Memos, Files, shared messages, or Recently Deleted.

Publisher disclosure: LocalOneLabs makes LocalOne VoiceVault. The built-in app lock may be sufficient if you do not need separate storage.
