Overview
- The rollout is live on iOS and the web, with Android builds in final testing for an imminent release.
- Chat adds end-to-end encryption for messages, groups and media, plus voice and video calling, file sharing, message editing and deletion, disappearing messages, and screenshot controls.
- Legacy direct messages are migrated into a unified inbox so users retain their previous conversations.
- X’s help center discloses that message metadata is not encrypted and the system currently lacks protection against man-in-the-middle attacks.
- Activation uses a four-digit PIN to encrypt private keys, a choice flagged by researchers as weak, and X says verification tools and voice memos are in development.
