WhatsApp explains how the security of transmitted text, voice and video messages is ensured even without the use of a smartphone, despite the multi-device functionality. For this purpose, the basic security structure of WhatsApp has been changed.
Until now, when a message was sent via a smartphone connected via a PC or web browser, the user’s identity was verified and the associated end-to-end encryption was carried out. With the “Multi Device” this is now done independently from the smartphone. Nevertheless, all messages, media, and calls are protected from unauthorized eyes by final-to-final encryption.
WhatsApp explains that “each message is encrypted individually using a pair of encryption sessions set up on each device. Messages are not stored on the server after delivery” and adds: “The same scalable sender key encryption program of the signal protocol is still used for groups.”
