Although WhatsApp is yet to provide official details, WhatsApp beta tracker WABetaInfo has reported that the end-to-end encryption available on WhatsApp will be compatible with its upcoming multi-device support.
Earlier this month, Mark Zuckerberg mentioned in an alleged conversation with WABetaInfo that chats when using multi-device support on WhatsApp will still be end-to-end encrypted. Screenshots shared by WABetaInfo showed that the Facebook CEO stated that the company solved the challenges involved in implementing end-to-end encryption in an “elegant way” to make sure that the chats between users are protected even when using the messaging app on multiple devices.
