The app lock feature of iPhone and iPad allows you to authenticate with a Face ID or password before launching a specific app, even if your device is unlocked. This feature is very practical for users who focus on security and privacy, as well as for general users.

This application locking feature supports both Face ID and password, whichever authentication method you use. If you are not familiar with this feature, read on and you will soon learn how to enable and lock apps on your device.

How to lock an app with a Face ID or password on your iPhone

You must have iOS 18 or iPadOS 18 or later to use the app lock feature. The operation method is as follows:

1. Go to the home screen of your iPhone or iPad and find the app you want to lock.

2. Press and hold the app you want to lock until a pop-up menu appears, then click Require Face ID or Require Password, depending on your device security settings.

3. Confirm that you want to enable the app locking feature for this specific app.

4. The feature takes effect immediately, but you can try opening the app to confirm that it works properly. If you are using Face ID and are using the device, authentication will be done soon and the application will open. So, to test the Face ID feature, try covering the camera and then opening the app. If you use a password instead of a Face ID to protect the device, the Password Input screen is displayed.

You can repeat this process to lock as many applications as you want on your device. Again, this is the second layer of protection for specific applications, in addition to the wider device protection provided by Face ID or password (yes, if you don't want to use this feature for any reason, you can use all iPhone devices without Face ID).

This feature is not only an additional security mechanism, but also helpful for parents, grandparents, and other users who want to lock a specific app to prevent it from being used on the device. Additionally, with app lock enabled, you can unlock your iPhone or iPad and then let others use the device while knowing that a particular app is protected and locked.

How to remove app locks on your iPhone or iPad?

Removing app locking is as easy as enabling app locking. Simply tap and hold the locked app and select "No Face ID required" or "No Password required" from the pop-up context menu, depending on your specific device security settings.
