How to Use App Lock on Pixel with Android 17

Android 17 brings a native App Lock feature to Pixel devices. This lets you protect individual apps with your fingerprint, face unlock, or PIN without relying on third-party tools.

The feature returned in Android 17 QPR3 Beta 3 after earlier testing. It hides notification content for locked apps and removes their widgets and shortcuts.

What App Lock Does on Android 17

App Lock adds an extra authentication layer. When you open a locked app, Android prompts for your screen lock credentials.

Google notes that AI agents and services you previously allowed can still access the app’s data. Locking an app does not revoke those permissions.

Notifications from locked apps hide their content. Widgets and home screen shortcuts for those apps are removed.

How to Enable App Lock on Your Pixel

You need a Pixel enrolled in the Android Beta Program running Android 17 QPR3 Beta 3 or later. Stable release timing depends on Google’s rollout schedule.

First, confirm you have a screen lock set. Go to Settings > Security & privacy > Screen lock and choose a PIN, pattern, password, or biometric.

Step 1: Access App Lock Settings

Open Settings. Tap Security & privacy. Scroll to find App lock. If it is not visible, search for “App lock” in Settings.

Step 2: Select Apps to Lock

In the App lock menu, toggle on the apps you want to protect. Common choices include banking apps, messaging apps, and photo galleries.

You can also long-press an app icon on the home screen or in the app drawer. Select App lock from the menu that appears.

Step 3: Test the Lock

Exit Settings and open one of the locked apps. Android should prompt for authentication before the app loads.

After unlocking, the app works normally until you leave it. Recents may hide the preview for locked apps.

Managing Locked Apps

Return to Settings > Security & privacy > App lock to review or change your list. Toggle apps off to remove the lock.

If you lock an app that has widgets, those widgets disappear from the home screen. You must unlock the app to restore them later.

Tips for Better Privacy

Combine App Lock with Android’s Private Space for stronger separation of sensitive apps. Private Space creates an isolated profile.

Review which AI agents have access to your apps. App Lock does not block them if you granted permission earlier.

Keep your screen lock strong. App Lock uses the same credentials as your device unlock.

Conclusion

App Lock on Android 17 gives Pixel users a simple way to protect individual apps. Enable it from Settings or by long-pressing an icon. Remember the limits around AI agents and notifications.

Test it on a beta build first if you are enrolled. Stable availability will follow Google’s QPR schedule.
