No one will be able to access messages or calls thanks to end-to-end encryption, with this new system communications will only be visible to the two recipients.
On the official website it appears:
“Today, more than a billion people use Whatsapp to stay in touch with their friends and family around the world. And now, every single person of these can speak freely and in total safety on Whatsapp “.
Whatsapp becomes inaccessible. This new technology will activate automatically when you and the recipients of your messages use the latest updated version of the app.
So if you too were intrigued by the messages that are appearing on the app in these hours, this is the reason!
