Share

Spotted by 9to5, the feature is available to iPhone users with the WhatsApp version, 2.19.20.

The description for the new update on the App Store reads: "You can now require Face ID or Touch ID to unlock WhatsApp".

To add Face ID or Touch ID on WhatsApp for iOS, here's what you need to do.

According to the report by WABetaInfo, users can also set the time duration before which the app locks down WhatsApp. The latest update brings the anticipated biometric authentication that allows users to lock the WhatsApp on their iPhone models by deploying the native Face ID or Touch ID. You can't lock select chats within the app yet but even an app-wide lock method is a useful feature.

To enable the feature, simply go to Settings Account Privacy and enable Screen Lock. You can also choose whether you want the biometric authentication requirement immediately or after an interval of a minute, 15 minutes, or an hour.

There's no password backup option, which means that only your fingerprint or face will unlock the app.

"The feature is now only on the iOS app, and adds a new feature to the Privacy menu in users" settings.
