WhatsApp users who update to the latest version of the messaging application on iOS will find a new configuration lurking in the Privacy menu that adds support for Apple's biometric authentication technologies.
WhatsApp users on iOS can now take advantage of Apple's biometrics for an additional layer of security
Under the new configuration, called "Screen lock", users of WhatsApp on iOS can access another menu to add an additional layer of security by requiring their facial biometric or a fingerprint to unlock the messaging application.
IPhone users are offered the possibility of "Require Face ID" or "Require Touch ID", depending on the hardware of your phone.
The change, in version 2.19.20 of the WhatsApp iOS application, is listed as:
Now you can require Face ID or Touch ID to unlock WhatsApp. Touch "Settings"> "Account"> "Privacy" and enable Screen lock.
While WhatsApp uses the respected Signal Protocol to protect users' communications through end-to-end encryption, the best encryption in the world can not offer any protection if a person gains possession of their unlocked device, since it can open the Application and read everything in plain text.
Therefore, the lack of a native blocking option on WhatsApp has been a fairly large security oversight, but one of the messaging giants at least has now been rectified on iOS.
Although the configuration is not enabled by default, and is somewhat hidden in the menus, it is unlikely that users with less security knowledge will realize that it is there.
There is also no native option in WhatsApp to add any kind of access code to the application, which would offer a universal "extra security" option that could work on Android and iOS. (Probably the main Facebook of WhatsApp is not a fan of the added "friction" that such a configuration could bring).
Although several third-party applications can be downloaded and used to require an access code before other applications can be opened, a native access code option would increase accessibility and reduce potential security concerns about the use of third-party downloads for what really should be a central function.
