   End-to-end encryption (E2EE) is important. However, on self-hosted or otherwise trusted servers, the client-to-server transport layer presents a much larger attack surface. It’s the first hurdle an adversary must overcome before they can attack E2EE.

   That’s why #Conversations_im includes advanced MITM detection called Channel Binding. Turn it on today!

   It’s optional for now because not all servers support it. Talk to your admins.

   Neither @matrix nor @delta offer comparable protection.
