New EU rules mean WhatsApp and Messenger must be interoperable with other chat apps. Here’s how that will work.

Got it from here : https://infosec.exchange/@mattburgess/111885761552024420

NEW: WhatsApp will soon make it possible to chat with people who use other messaging apps. It’s revealed some more details on how that will work.

— Apps will need to sign an agreement with Meta, then connect to its servers.

— Meta wants people to use the Signal Protocol, but also says other encryption protocols can be used if they can meet WhatsApp’s standards

— WhatsApp has been testing with Matrix in recent months, although nothing is agreed yet. Swiss app Threema says it won’t become interoperable

    So if Meta <-> Signal interoperability gets implemented and I have a hypothetical group chat with 5 Signal users and 1 WhatsApp/Messenger user, all the messages would be sent to Meta? I don’t like it

      Simple solution to that is not to add people. Am assuming should that happen Signal will add highlight of sorts to warn about users from other networks.

        How do I know that WhatsApp isn’t performing client-side scanning of messages? Meta has been doing it before, on Messenger
