WhatsApp, which recently caught inadvertently disclosing its users to third parties, will receive fingerprint authentication support in the near future. The corresponding information was found in the beta version of the messenger. Initially, the innovation will be available only to users of devices running Android, but later – until the exact dates have been disclosed – it will also reach iOS.
It is reported that the ability to protect their messages in WhatsApp with a fingerprint (or a password, if there is no fingerprint sensor or the user chooses not to use it) will be the owners of all smartphones running Android Marshmallow or newer. But using facial recognition technology for identification in the framework of the messenger – even if your smartphone is equipped with a hardware scanner – will not work.
Why you shouldn’t protect WhatsApp with a fingerprint
In my opinion, the protection of the messenger with fingerprints will not be such a significant innovation. If a fingerprint has already been added to the memory of your smartphone, other than yours (for example, a family member), it will automatically get access to all your correspondence, even if you didn’t add it to the list of authorized representatives. Therefore, the only way to truly secure your correspondence from prying eyes (even if they are your relatives) will be using a password.
At the same time, I strongly doubt that most users will prefer to enter even a four-character combination each time to enter the instant messenger. Despite the seemingly insignificant time required for entering a password, this will change your perception of interaction with WhatsApp for the worse. By setting a password, you actually lose your ability to have quick access to your messages, which is often more important than respecting imaginary privacy.
