WhatsApp has finally made the fingerprint lock feature for Android beta users. The new app authentication method is available on the 2.19.221 Android beta version.
As mentioned, the fingerprint lock option is enabled in the Android beta version 2.19.221, users will need to enable it in Settings as it is disabled by default, and this feature will allow users to add a layer of protection to their app chats, keeping lurkers at bay.
There’s also a new ‘show content in notifications’ option added allowing users to decide if they want to show or hide message and sender preview when the fingerprint lock is enabled.
When enabled, users will need to use fingerprint authentication to unlock WhatsApp and gain access. There are three options for ‘automatically lock’ to choose from – immediately, after 1 minute, and after 30 minutes. Users can choose from these options according to their preferences. Choosing the’ immediately’ option will require the user to fingerprint authenticate every time they close and open the app. Notably, the feature requires the phone to be running Android Marshmallow or higher, and feature a fingerprint scanner.
