"X has revealed Chat, an encrypted upgrade to the platform's direct messaging service. It also includes support for video and voice calls, disappearing messages, and file sharing. The company announced Chat on Friday, and it's available now on iOS and the web, with an Android version coming "soon." It replaces X's existing messaging system, though your old messages should be carried across."
"X says that Chat supports end-to-end encryption (E2EE) for both messages and files, though a support page notes that this doesn't cover message metadata - such as who received it, or when it was sent. There's also no protection against man-in-the-middle attacks, the company admitting that if "a malicious insider or X itself" compromised an encrypted conversation, there would be no way for users to know, though ways to verify message authenticity and device identity are coming."
Chat is an encrypted overhaul of X's direct messaging, available now on iOS and the web with Android arriving soon. The feature replaces the existing messaging system and should carry over prior messages. Chat offers end-to-end encryption for messages and files but excludes message metadata and lacks protection against man-in-the-middle attacks. The company acknowledges that a malicious insider or X itself could compromise conversations, and plans tools to verify message authenticity and device identity. Additional privacy controls include disappearing messages, screenshot notifications or blocks, editable and deletable messages, voice and video calls, and forthcoming voice notes.
