“The native Touch ID and Face ID authentication for WhatsApp puts an additional layer of security on the app, but doesn’t work on individual chats”
Back in October last year, it was reported that WhatsApp users on iPhones would soon get the ability to use Face ID or Touch ID as native authentication on the messaging platform. Well, the feature has finally started rolling out today. A new update that pushed the app’s version number to v2.19.20 has enabled the handy feature over the weekend. With this, iOS users can choose to necessitate biometric identification to open the app, although it will not work on specific chats within the app.
To enable the Face ID or Touch ID, you’ll have to first update to the latest version of WhatsApp from the Apple App Store. Once the latest version of the software is installed, navigate to Settings –> Account –> Privacy and tap on “Screen Lock” at the bottom. You will see the ‘Require Touch ID’ or ‘Require Face ID’ option, depending on your phone. Turn it on and choose one of the required options for timing and you will be good to go.
It is worth noting that quick replies and notifications will still be available without lock so the authentication would only be required when firing up the app. Apart from that, there seems to be no additional feature with the latest update. Also, the same feature isn’t yet available for Android and it is not known when it will be available, if at all, in the future.
The Facebook-owned chat app is used worldwide and was in the news recently after reports that its messaging service would be unified with Messenger and Instagram, all of which are owned by Facebook.
