    The much-awaited biometric unlocking feature of WhatsApp is finally here, on WhatsApp for iPhone. The build version 2.19.20 has received this feature which lets you add an extra layer of security to the application through Face ID and Touch ID. The new authentication system works similarly to the one found on Outlook and Signal iOS apps.

    This, however, doesn’t lock individual WhatsApp chats—it just lets you open WhatsApp with your biometrics. It also lets you view WhatsApp notifications with the body of the message as well as receive or decline WhatsApp calls.

    To enable this feature, you need to open WhatsApp and then go to Settings --> Privacy --> Screen lock. Now you’ll find the option to let you unlock WhatsApp through Face ID or Touch ID. Further, you get to choose to be prompted about this immediately or after an interval of a minute, 15 minutes or an hour.

    To start using this feature you’ll have to update your WhatsApp to the latest version (build v2.19.20). Depending on your settings, it will be updated automatically or manually. To manually update the app, go to the App Store, search for WhatsApp and check if your device has received the update. The feature is still in the rolling out phase, so it might take a while for your device to receive the update. WhatsApp for iPhone is 137.7MB in size and is compatible with iPhone models running iOS 8.0 and above.

    The feature is also rumoured to make its way to Android devices soon.
