The instant messaging application WattsUp is currently working on fingerprint authentication to prevent other users from seeing users' chats. Once this feature is enabled, users will need to authenticate, and a similar feature available on the app will be reported on the iPhone. This means that there will be two methods of authentication, namely "fingerprint, fingerprint".
It will not only be for the iPhone, where users of the other Android system will have fingerprint authentication, without any fingerprint authentication in WattsApp. According to WABetaInfo, still interested in the WTSAP test, this feature is under development. Available on the WhatsApp 2.19.3 test version but this option is disabled by default.
More: Watts on Android supports sending 30 audio files at once.
The feature will also be available in the application settings, especially in the Privacy tab. Once activated, the application will be completely closed, so it will not be used to lock specific conversations.
