WhatsApp has spent more than a decade operating on a simple rule: no phone number, no account, no conversation. That rule just got a significant exception. The Meta-owned messaging service is introducing guest calling, which lets people without a WhatsApp account join voice and video calls straight from a computer browser.
The mechanics are straightforward. A WhatsApp user opens the Calls tab, taps the plus icon to generate a call link, and shares it however they like. Whoever receives it can open the link in a desktop browser and request to join. Nobody walks in uninvited, though. Guests land in a waiting room until the host admits them, and the host can remove them at any point during the call.
Guests also get a deliberately restricted role. They can’t initiate calls, only accept invitations. They can’t send messages, add other participants or see anyone’s phone number. What they can do is share their screen, raise a hand and react with a thumbs-up or heart, and there’s no cap on how long they can stay connected. It’s a sensible balance that gives outsiders enough to take part in a meeting without opening a backdoor into anyone’s contact details.
WhatsApp says its calls remain free and end-to-end encrypted, with support for up to 32 participants. What hasn’t been made explicit is whether every one of those guarantees applies identically when someone joins through a browser rather than the app. For a platform that leans heavily on its encryption credentials, that’s a detail worth clarifying.
None of this is a new idea. Apple has let people join FaceTime calls from a browser, without an Apple device or account, since iOS 15. Google Meet, Zoom and Microsoft Teams have relied on link-based joining for years. WhatsApp is catching up rather than leading, but its scale changes the equation. When the app most of your contacts already use can host a call with the one person who refuses to install it, the case for juggling a separate video platform weakens.
That ambition becomes clearer with what’s planned next. WhatsApp intends to add Google Calendar and Outlook integrations later this year, allowing calls to be created directly from scheduled events. That places it squarely inside the meeting invite, the territory Zoom and Teams have long owned.
The feature also fits a broader pattern. WhatsApp has already introduced usernames to keep phone numbers private, and Signal is testing number-free registration in beta. The phone number as identity is slowly loosening its grip on messaging.
Regional availability hasn’t been confirmed, so users in the UAE and wider Middle East should update the app and check the Calls tab for the call-link option.
