XChat launch raises serious privacy and security doubts

🔒 Elon Musk’s XChat launched on iOS in April 2026 as a purportedly private messaging alternative, but its encryption model and key handling have raised alarm among experts. XChat stores users’ private keys on servers protected by HSMs and uses four-digit PINs to encrypt those keys for multi-device sync, a design that undermines classic end-to-end guarantees. Practical issues — message requests sent without E2EE, confusing PIN prompts, and weak brute-force protection — further complicate user security. The net result: XChat offers convenience at the cost of meaningful privacy assurances.
