WhatsApp is finally rolling out fingerprint unlocking to Android phones, some 10 months after the feature first reared its head in an early Android beta build.
It’s worth noting here that WhatsApp has already introduced biometric security to its iPhone app, having added support for Face ID and Touch ID back in February. Touch ID, which involves using your fingerprint to authenticate an app, is available on the iPhone 5S through to the iPhone 8 / 8 Plus, at which point Apple replaced Touch ID with its facial recognition system instead.
So while we already knew that WhatsApp was working to bring biometric unlocking, today’s announcement finally brings it to the masses. This is a notable development for WhatsApp, given that one of its core selling points is the security it offers through end-to-end encryption — fingerprint unlocking makes things even more secure, as it encourages the user to lock the app down on their device even if the device itself is unlocked.
How it works
To activate the feature, head to the app’s settings, then to to “account” and “privacy.” Toggle the “fingerprint lock” switch, and then choose when WhatsApp should automatically lock itself: immediately, after 1 minute, or after 30 minutes.
Users can also choose to view the messages in push notifications, which means that anyone else would be able to view it too, though they wouldn’t be able to open the WhatsApp app itself.
All that’s really missing now on Android is the ability to unlock WhatsApp using facial recognition technology. While Android phones have offered “face unlock” features in the past to unlock devices, Google’s new Pixel 4 takes things to the next level by allowing users to authorize themselves in a handful of third-party apps, including password managers and banking services.
As more Android device makers jump on board with face unlocking smarts, we can likely expect WhatsApp to embrace this functionality in the future.
