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
Only if Signal decided to apply for connection, which I doubt they’ll do.
It would be cool tho if you could. I don’t wanna use WhatsApp but I’m basically forced to because everyone else in my family uses it.
Yeah, for me my family and close friends have no problem because I explained and told I am not going to use Facebook products. But when meeting new people, especially groups of people there is a big barrier.
