The WhatsApp messenger received an upgrade to iOS to install biometric entry to the application. Now iPhone 8 owners and older models Touch ID, and iPhone X, XS and XR can use Face ID to allow chat rooms to be enabled.
To use the new action, you must update WhatsApp to version 2.19.20, go to "Settings" -> "Account" -> "Privacy" and enter the "green" message.
Users will be able to read on the blue screen and use the system's early response feature, but logging in to the application will only be available through a biotyteal test.
Previously, vulnerability was found in WhatsApp that allows the translator to receive messages from the back copy.
