Overview
- The test is rolling out to selected Android and iOS beta users, and WhatsApp has not given a date for a wider release.
- Invitation links sent by SMS or email open WhatsApp Web in a browser for one‑on‑one chats that use temporary identifiers and end‑to‑end encryption.
- Guests can send only text messages and receive no notifications, with media sharing, voice or video calls, and group chats not supported.
- Guest sessions are clearly labeled for WhatsApp users, invitees can be blocked, and chats automatically expire after ten days of inactivity.
- Guest identities are not verified, so links can be forwarded or opened by unintended recipients, a trade‑off noted as Meta faces EU Digital Markets Act pressure to broaden access.
