AI-summarised brief · reviewed before publication

WhatsApp is fundamentally restructuring user identity and privacy protocols in 2026, introducing usernames to allow messaging without exposing phone numbers, though numbers remain required for account registration. Meta opened global username reservations on June 29, 2026, with full rollout scheduled later this year. Handles range from 3 to 35 characters, and no public directory exists, requiring exact handles for contact initiation. To prevent impersonation, Meta is reserving names for public figures early. Concurrently, Advanced Chat Privacy restricts automated data extraction from sensitive conversations, though it does not block screenshots. Security enhancements include passkey adoption, with over one billion users switching from PINs by August 2026. Additionally, Meta AI now features Incognito Chat, launched in May 2026, which utilizes Private Processing for self-erasing, private interactions. These updates represent the most significant architectural shift since end-to-end encryption became standard, moving the platform beyond phone-number-centric identification toward a more privacy-focused, AI-integrated ecosystem for its three billion users.
