WhatsApp on iPhone includes an option to lock the app with your device's Face ID or Touch ID authentication. So turning on Screen Lock for WhatsApp application on your iOS device is a lot easier than you may think. You can do this right within the app. Simply follow the steps below to get started.

Step 1: Open WhatsApp on your iPhone.

Step 2: This will take you to the Chats section of the app. Tap on Settings located at the bottom-right corner of your screen.

Step 3: In the Settings menu, choose the Account option.

Step 4: Next, tap on Privacy to adjust your privacy settings for your WhatsApp account.

Step 5: Here, scroll down to the very bottom and tap on the Screen Lock option as shown in the screenshot below.

Step 6: Now, you can use the toggle to enable Face ID or Touch ID for unlocking WhatsApp depending on the device you own. Additionally, you can adjust the duration WhatsApp can remain on standby before Face ID or Touch ID is required again. As you see, there are four different options to choose from: Immediately, After 1 minute, After 15 minutes, After 1 hour.

There you go. Now you’ve learned how to lock WhatsApp on iPhone with Face ID and Touch ID.

Keep in mind that you will still be able to reply to messages from notifications and answer voice/video calls even if WhatsApp is locked. If you’re unable to unlock with Face ID/Touch ID or if the authentication fails, you’ll be prompted to type in your device passcode.
