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

    WhatsApp, Google Messenger, Facebook Messenger and Skype all implement the same Signal protocol.

    The article’s title is misleading, and did not explain how it would work at all.

    Like, will the protocol also add logins for different services? I remember having a messenger app a while ago (Trillian), which would merge MSN, ICQ and other chat platforms into a single experience.

    I can sorta get how DMs will work. Group chats may be much harder to implement.

      I had all but forgotten about Trillian! Man, that was huge in my circles back in my youth. Such nostalgia reading that name again.

      Also to add a very important question: will Facebook then be able to harvest all of our Signal metadata like they do for WhatsApp?

        Hopefully the opposite is true. There’e end-to-end encryption and if the client isn’t written by meta, then meta can’t intercept after decryption.

        Being able to use meta’s chat platform without any of their code being executable on your device is a big improvement. They can’t scrape your contacts and data at all.

      Trillian? A while ago? Maaaan, that’s almost two decades ago… Nostalgia just hit me
