How to Lock WhatsApp on Android

If you use Android and want to lock your WhatsApp, do not worry! This section will discuss how to lock WhatsApp on an Android device.

Step 1: Employ the Built-in App Lock Feature

Some Android devices offer a built-in feature to lock individual apps directly:

1. Access Phone Settings

Locate the “Settings” icon on your home screen or app drawer and tap on it. This icon typically looks like a gear or a set of sliders.

2. Locate the App Lock Feature

Inside the Apps or App Management menu, look for a feature that says “App Lock,” “Privacy,” or something similar.

3. Choose WhatsApp to Lock

Once you’re in the App Lock or similar menu, you’ll see a list of all the applications installed on your device. Scroll through the list and find WhatsApp. Tap on it to select it for locking.

4. Activate the Lock

After selecting WhatsApp, you will be prompted to choose the type of lock you want to use. You can typically choose between a pattern, PIN, or fingerprint lock.

Step 2: Using Third-Party App Lockers

If your phone doesn’t have an in-built app locking feature, you can download a third-party app locker from the Google Play Store:

  1. You need to download an app locker such as AppLock or Norton AppLock.
  2. Now, install the application and follow the setup guidelines.
  3. Next, include WhatsApp to the list of applications you want to lock.
  4. After that, configure your preferred security setting (Pattern, PIN, or fingerprint).


  • App lock is only accessible on Android devices with a fingerprint sensor operating Android 6.0+ and supporting the Google Fingerprint API.
  • You can only use facial recognition on Android devices with a face scanner.
  • Face and fingerprint authentication take place entirely on your gadget. By design, WhatsApp cannot access the biometric details saved by your device’s system.

Within the Privacy settings, you will see an option called “App Lock.” Tap on this to access WhatsApp’s screen lock settings.

You’ll find a toggle switch next to “Require Face ID.” Flip this switch to the on position. This will enable Face ID for WhatsApp, meaning that the app will now require facial recognition to open.

How to Lock WhatsApp on the Web and Desktop

Locking WhatsApp on the web and desktop is not supported directly through the application; however, you can secure your web sessions using browser extensions. It’s important to note that using browser extensions always carries some risk, so choose a reputable extension and read user reviews before installing. Here are two methods you can use:

Method 1:

1. Choose the Right Extension

Extensions like “Session Buddy” and “Lock PW” are designed to manage and secure your browser sessions, including those used for WhatsApp Web.

2. Install the Extension

Once you choose an extension, click on ‘Add to Chrome’ to install it. After installation, there will usually be a setup wizard or a set of instructions to guide you through configuring the extension. Follow these guidelines carefully to ensure the extension functions properly.

3. Lock Your WhatsApp Session

After setting up the extension, navigate to WhatsApp Web and log in as usual. You can then activate the extension to lock this session. With the lock in place, you must enter a password to access your WhatsApp messages, effectively preventing unauthorized access.

Method 2:

1. Access Settings

Start by opening your WhatsApp on the web or desktop. Click on the three-dot menu at the top of the window to access more options, and select the “Settings” option from the dropdown menu.

2. Navigate to Privacy Settings

In the Settings menu, click “Privacy” to open the privacy-related settings.

3. App Lock

Find and click the “App Lock” option in the Privacy settings. This feature may not be immediately visible as it depends on the updates and version of the application you are using.

4. Enable the App Lock:

Hit this App lock option and set the password to complete the procedure.

5. Set a Strong Password

Once you click on App Lock, you will be prompted to set a new password. Choose a strong password that is difficult to guess. A strong password typically includes a mix of letters, numbers, and special characters.

6. Activate the Lock

Finish the setup by clicking the “OK” option to activate the App Lock. Your WhatsApp on the web or desktop will now require this password every time it is accessed, providing an extra security layer to protect your private conversations.
