In addition to this novelty, Zuckerberg has anticipated two other additions: Disappearing Mode e View Once, both to be released in a couple of months.
With the first, the messages received and sent will be deleted after a period of time to choose between 24 hours or 7 days. With View Once, on the other hand, after a user has viewed the multimedia contents in a chat, they will disappear automatically and permanently.
Zuckerberg confirmed a WABetaInfo that multi-device support will not compromise end-to-end encryption, which currently protects messages between two communicating devices, through a key consisting of a common and a unique part, present on the sending and receiving smartphones.
“It was a great technical challenge to get messages and content to sync properly across all configured devices, even when the phone’s battery runs low, but we have solved this problem and we can’t wait to roll out the update,” he announced. .
For some time now, WhatsApp’s main competitor, Telegram, already allows you to set up the same account on multiple phones or tablets, as well as send self-destructing chat messages.
