With the launch of iOS 18, Apple finally introduces a long-awaited feature: App Lock. This tool allows users to lock individual apps using Face ID, Touch ID, or a device passcode—giving iPhone owners more control over their privacy without needing third-party apps. The addition of iOS 18 App Lock marks a major shift in how Apple approaches in-device security and user data protection.
What Is iOS 18 App Lock?
App Lock in iOS 18 allows you to add biometric authentication to specific apps on your device. Once enabled, anyone trying to open the locked app will be prompted to authenticate using Face ID, Touch ID, or your iPhone passcode. This feature applies to native apps and many third-party apps as well.
Until now, iOS lacked a native way to lock individual apps. Many users relied on Screen Time workarounds or third-party apps with limited functionality. Now, the system-level support brings convenience and security in one seamless package.
How to Enable App Lock in iOS 18
To turn on App Lock:
- Go to Settings > Privacy & Security
- Select App Lock
- Choose which apps you want to secure
- Select your preferred authentication method
Once locked, the app icon stays visible, but its contents remain inaccessible without authentication. This is useful for messaging apps, health data, banking apps, and even Notes or Photos.

Why This Feature Matters
Privacy is a growing concern for smartphone users. With more apps holding sensitive data—from finances to personal chats—locking your phone is no longer enough. App Lock gives users a second layer of defense, especially useful in shared environments or during momentary access to your phone by others.
Compared to Android, which has offered similar tools via third-party apps or OEM layers, Apple’s solution is deeply integrated into iOS. It doesn’t rely on extra apps or services, which also improves trust and performance.
Limitations and What’s Missing
As of the iOS 18 developer beta, some third-party apps may not yet support App Lock. Apple has promised broader API support in future updates, allowing more developers to take advantage of the feature.
Also, users can’t yet customize lock durations or notifications per app. For now, it’s a simple lock/unlock feature, but future iOS updates could enhance its flexibility.
Final Thoughts
iOS 18 App Lock delivers what users have been asking for—a simple, secure, and native way to protect individual apps. While still early in its rollout, this feature significantly boosts privacy for everyday iPhone users.
Expect it to become a go-to tool for managing digital boundaries, especially as more people store sensitive content on their phones. Apple continues to build trust by focusing on security that’s easy to use and hard to break.
