Overview
- WhatsApp is building a guest-calls feature that would let people without a WhatsApp account join voice or video calls by opening a shared link in a web browser.
- When a guest opens the link, WhatsApp Web generates a unique session identifier that is used to create encryption keys so the company describes the calls as end-to-end encrypted.
- Hosts must manually approve every guest before they join and keep standard controls to remove participants or end the call for everyone.
- Guest calls extend WhatsApp's existing guest-chat technology to real-time, ephemeral conversations that do not persist after the call ends.
- The feature is under development, not available to beta testers, and has no announced release date, a change that could lower friction for contacting non-users while raising verification and moderation trade-offs for hosts.
