Quick Tip: Use Face ID to Lock or Unlock Any iPhone App

iOS 18 finally lets you lock any iPhone app with Face ID, not just the ones developers choose. Here’s how to set it up and keep your apps private when you share your phone.

Ever hand your iPhone to someone and feel uneasy about what they might open? With iOS 18, you can lock any app with Face ID, so only YOU can open those specific apps.

Here’s how to set it up:

• Long-press on the app icon until the menu appears

• Tap Require Face ID

• Confirm by tapping Require Face ID again

Now that app won’t open without your face to confirm it’s you. It’s a quick way to keep your private apps secure, whether you’re lending your phone to family, friends, or coworkers.
