Thanks to mobile fingerprint technologies, we can go now thinking of unblocking WhatsApp with our finger in order to protect the app from the gaze of third parties. In the beta of the chat app that option is already available, although in a hidden way.
That said about fingerprint sensor technologies, there are some safer than others. Especially that of the Galaxy S10 + with FIDO standard thanks to having an ultrasonic sensor unlike the optical ones that we see in the rest of the terminals.
With all the attention that the dark theme of WhatsApp is receiving in the beta, the one that we can unlock the app by fingerprint of our finger is also of great interest; especially in those mobiles like Samsung's in which it is scanned with ultrasound instead of scanning, as if taking a photo, with the optician.
WhatsApp fingerprint protection is hidden in the new beta version of WhatsApp, so we are already eager to try it when it is a reality in the stable. In this way we can prevent other people's eyes from entering our favorite chat app to look at messages and others. That is, you will force your finger to be used to open it.
It is not the first app that already allows the use of the fingerprint, but there are quite a few that allow adding this extra layer of security to make it difficult for the onlooker on duty. Although the interesting thing is to wait for the next beta and check if WhatsApp will already have the possibility to use the fingerprint sensor to be able to unlock one of your favorite apps, or the one you use the most, on your mobile. Some patience.
