WhatsApp has recently introduced a ‘Fingerprint lock’ feature on its platform for Android beta users after introducing the screen lock feature for iOS beta users.
With this feature, users will have to use their Fingerprint to unlock or open their WhatsApp.
However this new development does not affect the receiving of calls, this is to say that user will be able answer calls even when WhatsApp is locked.
To access the new feature, users will have to update their WhatsApp version on Google Play Store to the 2.19.221 Android beta version.
After this update, user can then enable the new feature by opening WhatsApp “Settings” and then go the “Account” and then to the “Privacy” section where one can spot the “Fingerprint lock”.
Once you have the option, it’s fairly straightforward. WhatsApp will talk to your phone and allow your saved biometric credentials to work with the app, then you’ll be asked whether you want it to lock as soon as you close it or wait for 30 seconds/1 minute.
There’s also an option that allows you to hide notification content when locked.
