How to Lock Apps on iPhone with iOS 18 Using Face ID or Passcode
Share
With iOS 18, Apple finally introduced a feature iPhone users have been requesting for years — the ability to lock apps using Face ID, Touch ID, or a passcode. This new privacy tool helps you protect sensitive apps like Photos, Messages, or social media apps from unwanted access.
In this article, you’ll learn how to lock apps on your iPhone running iOS 18, what happens when an app is locked, and how to make the most of Apple’s new security features.
What Is App Locking in iOS 18?
App locking allows you to protect any app on your iPhone. When you open a locked app, the system will ask for Face ID, Touch ID, or your passcode. Without it, the app cannot be accessed, and its content remains hidden.
This feature is built into iOS 18 and does not require any third-party software.
How to Lock Apps on iPhone (Step-by-Step)
To enable app locking on your iPhone:
- Go to Settings > Privacy & Security
- Tap Locked Apps
- Tap Add Apps and select the ones you want to lock
- Confirm using Face ID or your passcode
Now, every time you open those apps, iOS will require biometric authentication.
How Locked Apps Work on iPhone
Once locked, the app stays visible on your home screen. However, tapping it brings up a Face ID or passcode screen. If authentication fails, the app will remain inaccessible.
Apps can be configured to lock immediately after closing or after a short delay. You can also choose to hide locked apps from search and the app switcher.
Why Locking Apps on iPhone Is Useful
This iOS 18 feature is helpful if:
- You want to keep your Photos, Messages, or social media private
- You share your phone with family or kids
- You use your iPhone for work and want to protect business apps
- You’re looking for more privacy without third-party apps
What You Can and Cannot Lock
You can lock most third-party and Apple apps, including Photos, Mail, WhatsApp, Telegram, and Safari. However, some system apps like Settings or Phone cannot be locked yet.
This feature works on iPhone 12 or newer models that support iOS 18.
Conclusion
App Locking in iOS 18 brings an extra layer of privacy and control to your iPhone. Whether you want to lock the Photos app with Face ID or protect your messages from curious eyes, iOS now gives you the tools to do it easily and securely.
