    Why Lock Apps on Your Android Smartphone

    Your mobile apps store more information about you than you might realize. Password managers, banking apps, and online messengers like WhatsApp offer built-in locking mechanisms. But social media apps (which contain the biggest amount of data about you by far) are easy to access for anyone who gets a hold of your phone.

    Locking apps on your smartphone doesn’t only help avoid sensitive information leaks but also prevents your children and other family members from accessing certain apps on your phone. You can restrict access to individual apps or all of them at once using the security settings of your mobile device or with the help of a third-party locking app.

    How to Lock Apps on Your Android Phone

    There are a few ways you can password-protect apps on an Android device. Which technique you choose will depend on the Android version of your phone, as well as whether you want to download and install apps on your smartphone.

    Use the Built-In App Lock to Lock Your Apps

    If you want to lock apps on Android without installing an app, you can use the built-in tool on your smartphone called App Lock. The App Lock allows you to protect individual apps with a password, fingerprint, or pattern lock.

    Depending which model of Android phone you have, the steps to enable the App Lock will differ slightly. You’ll find this tool if you dig around in your phone’s Settings. Here’s how to use App Lock on Xiaomi, Redmi, Realmi, Mi, and Poco Android smartphones.

    1. Open your phone’s Settings.
    2. Scroll down and select Apps.

    On Samsung phones, a feature called Secure Folder comes with the same functionality. You can use it to safely store your apps, media, and other files on your phone. This tool uses the Samsung Knox security platform for data encryption. To lock your apps using the Secure Folder on your Samsung device, follow the path Settings > Biometrics and Security > Secure Folder > Add Apps.

    Use Screen Pinning to Lock Your Apps

    One more way to lock your Android apps is by using screen pinning. You can use this tool to lock a particular app on your smartphone’s screen in open view. When someone attempts to close the app or go to the home screen, your lock screen will activate, asking for a password.

    For example, if someone opens your banking app after stealing your phone, screen pinning won’t allow them to close it and access any other apps on your phone. As long as you stay logged out of your banking app when you’re not using it, this should protect all of your important smartphone data.

    To get the most out of screen pinning and other security features, make sure to set a secure password or pattern as your screen lock.

    Here’s how to set up Screen Pinning on your Android device. The instructions may vary depending on the model of your phone and the Android version you have.

    1. Open Settings on your smartphone.
    2. Scroll down and select Password & security (Lock Screen and security or Biometrics and security, depending on your phone model).

    When you don’t need the app pinned anymore, unpinning it is easy. Press and hold Overview and Back icons simultaneously, and you’ll find yourself back on your lock screen.

    Use a Third-Party App to Lock Your Apps

    If you’re okay with installing yet another app on your smartphone, you can use a third-party app like the Norton App Lock to secure your Android apps.

    Norton App Lock is a security app by Symantec that allows you to protect applications and personal files stored on your device. The app is free and compatible with Android 4.1 and up. You download it from the Google Play Store and uninstall it at any time if you change your mind.

    After you install the Norton App Lock, all you need to do is to set up a master password and select all of the apps that you want to be locked on your phone. You’ll need to sync the app with your Google account in case you ever need to reset the password. If you forget the password, you’ll get a letter from Norton App Lock on your Gmail with a password reset link.

    Use a Launcher

    There are other ways to protect your app data from being accessed by the wrong people. You can set up a guest account on your smartphone or get a Launcher for your phone with the app lock functionality built-in.

    Launcher is like a theme for your mobile device. It’s the software that controls the interface activities of your phone, including your home screen, lock screen, keyboard, and some app functionality. Some launchers have the ability to lock individual apps for you. You can find the best Android launchers on Google Play Store.

    How to Lock Apps on iOS Devices?

    Apple has fallen behind Android in the matter of locking apps, and there are no built-in means to stop anyone from looking into the content of your apps on iPhone or iPad. The best you can do to lock apps on an iOS device is to set up a passcode, a Touch ID, and Face ID.

    You can also take advantage of the Screen Time feature and lock an individual app for a set amount of time on your screen. The same tool can also help you limit your screen time and motivate yourself to focus on different tasks.
