From now on, access to WhatsApp on devices with iOS can be protected by blocking by fingerprint (Touch ID) and facial recognition (Face ID) on mobile phones that have this feature. These biometric security functions work when you access the application from the start menu.
“WhatsApp for iPhone is passed to biometric security, something that currently can not be enjoyed on mobile phones with Android.”
The new security modes, which had already been observed in the beta, are available in version 2.19.20 of WhatsApp. Whether the fingerprint or facial recognition can be used depends solely on the iPhone version we have. Facial recognition is available on iPhone X and later.
This new security layer can be activated by entering Settings, and once there, in Privacy. Identification by fingerprint or facial recognition does not protect conversations individually, but affects the fact of opening the WhatsApp application.
The most jealous of your security will enjoy this new addition, but without a doubt, it can be slightly tedious to have to unblock WhatsApp (even if it only takes a few moments) each time you want to send or read a message.
Still, if you have notifications enabled, you can see and respond to messages without unlocking the application. The same applies to calls, which can be answered without having to put our fingerprint or use our face. Therefore, if this option is established, the notifications must be configured accordingly.
