WhatsApp possibly adding fingerprint lock to protect chats
Popular messaging service WhatsApp is supposedly testing a fingerprint lock feature around the Android form of the application for additional security.
Based on WABetaInfo, the feature was spotted in alpha way of WhatsApp for Android (version 5.19.3). The content also claims that the feature is going to be available first for devices running on Android 6..1 (Marshmallow) or later, before it’s folded to the iOS platform.
However it could actually take several weeks prior to the feature is formally launched for those Android users, WABetaInfo states. The web site adds the fingerprint lock is really a blanket lock around the entire WhatsApp application, and never for particular chats or contacts inside the application.
Users will have to register their fingerprint on their own device to make use of the feature, or maybe their fingerprint scanner is damaged, they might use other device credentials – like a PIN code – to lock the application, the content adds.
Users will have to authenticate their identity to spread out WhatsApp in the application icon or perhaps in the notification bar.
WABetaInfo also claims the Facebook-owned WhatsApp is apparently intending to integrate Face ID in addition to Touch ID to the iOS version, because the newest iPhone models (from iPhone X and then) don’t support fingerprint authentication.
However, the content adds this feature continues to be in development and won’t be accessible to iOS users in the near future.
The chat application already uses finish-to-finish file encryption for defense, which would behave as yet another layer of security.
