Facebook-owned WhatsApp is working on a fingerprint authentication feature to protect its users’ chats from being seen by others.
“After working to implement Face ID and Touch ID features on iOS, WhatsApp has finally started to work on the authentication feature on Android, using your fingerprint, the feature will be available within the app under the new section.
“Once you enable the fingerprint feature, WhatsApp will be completely protected from others to be seen. The user will need to authenticate his identity in order to open WhatsApp ( from the App icon, from the notification or from external pickers). It will protect the entire app, so it’s not used to lock specific conversations”.
This new WhatsApp privacy setting is apparently to be made available to devices that run Marshmallow ( or Android 6.0) and are equipped with fingerprint reader.
