"Back at FOSDEM in February we showed off how Matrix could be used for E2EE-preserving messaging interoperability as required by the Digital Markets Act messaging interoperability - and we announced that Element had been working with Meta on integrating with its DMA APIs in order to connect WhatsApp to Matrix."

Update on Native Matrix interoperability with WhatsApp

Matrix, the open protocol for secure decentralised communications

^{Matthew Hodgson (matrix.org)}

🇬🇧Consumer-hostile #Whatsapp messenger will soon be interoperable - we #Pirates ensured this via the #DMA. In the coming months, we will be able to switch to better and open messenger services such as Matrix and continue to communicate with our consenting Whatsapp contacts securely and end-to-end encrypted across platforms using the Signal protocol. Wired reports: https://www.wired.com/story/whatsapp-interoperability-messaging/

Facebook Messenger will also become interoperable, possibly iMessage too.
Anonymous use of the participating alternative messenger services remains possible, and Whatsapp only receives data on messages sent across platforms.

Even if Threema and Signal want to stay on the sidelines at first, I am confident that more and more messenger services will join in over time, because interoperability is the future and brings real competition and real freedom of choice!

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
