Popular messaging service WhatsApp is supposedly testing a fingerprint lock feature on the Android version of the app for added security.
According to WABetaInfo, the feature was spotted in alpha mode for WhatsApp for Android (version 2.19.3). The article also states that the feature will be available first for devices running on Android 6.0.1 (Marshmallow) or later, before it’s rolled out to the iOS platform.
