According to reports, WhatsApp is working on a fingerprint authentication feature to protect its users’ chats from being seen by others.
Once enabled, the authentication will be required for users to open the app. The Facebook-owned instant messaging service was recently reported to bring a similar feature to iPhone as well, supporting two biometric authentication methods – both Face ID and Touch ID.
Reportedly, this won’t be limited to iPhone, and users on Android will get fingerprint authentication, but no facial recognition based authentication, thanks to the lack of a widely used standard on the platform.
According to WABetaInfo, a fan site that tests new WhatsApp features early, the feature is current under development, and disabled by default in the Android 2.19.3 beta version.
