If the end-to-end encryption feature on WhatsApp wasn’t enough, the online chatting platform – WhatsApp has adopted biometric authentication feature that will now enable the user to lock the app on their devices. This way, only those will be able to launch the app using the Touch ID or Face ID feature built into their iPhone devices.
The above feature is available with the latest update, version 2.19.20 of WhatsApp dowloaded via the Apple App Store. Users will be able to enable the feature by clicking on “Settings” > “Account” < “Privacy“. There, users will have to toggle the ‘Screen Lock’ setting to the On position for the security feature to be enable on the device. This way, only those users will be able to launch the app whose credentials match with the Face or Touch ID details already stored in the device.
Users though will still be able to read WhatsApp notifications about any chat messages they might have received, with the option to make a quick reply as well.
Similarly, users will also be able to reply to WhatsApp calls without requiring authentication via FaceID or TouchID. However, to launch the entire app, users will have to go through the usual iOS authentication process as is required to unlock the device.
The latest update comes with no other feature than this and can also be considered to be a natural evolution of WhatsApp to use an authentication feature available anyway.
For users of iPhone X and above, read iPhone XS, iPhone XS Max and iPhone XR, its Face ID that would be relevant while all preceeding iPhone devices would be relying on Touch ID for securing the app.
Also, while the feature does make WhatsApp all the more secure by adding an extra layer of security, it wasn’t that the app was accessible to all so far. That is because the phone itself is protected by Face or Touch ID features and breaching any of those is almost impossible. Its only that the app has become a lot more secure henceforth.
