WhatsApp, the most popular messaging platform in the world, with over 2 billion active users globally, also has many tricks that not everyone knows about, but tricks that can be extremely useful for many people, and about which should, they being available on any iPhone and Android.
WhatsApp allows us to hide everything from our conversations from the eyes of the curious who use the application on iPhone and Android, and this is because there is a special function that gives us the option to protect the application with an access code, or the biometric security system integrated in phone by the manufacturer.
WhatsApp has an option in the settings menu that allows us to activate this system to use it in our devices, and thanks to it, no one will have access to the information from the conversations without knowing the access code, and protection is offered even in the case of preview for applications open in the background.
WhatsApp has implemented this functionality because there is an integrated biometric security system in most compatible iPhone and Android phones, and in general we are talking about functionality based on such systems, so it is important to use it in order not to risk we have the messages read by strangers.
WhatsApp is not the first messaging platform that offers this kind of functionality to users all over the world, something that of course you need to know, but if you haven't found out yet, well, go to the application's settings menu and activate biometric protection for messages.
