WhatsApp is opening its calls to people who do not have the app — or even an account. In an announcement published on 14 October 2026, the company introduced guest calls, a format in which a host generates a link and anyone who receives it can join from a desktop browser after typing a name and waiting to be admitted.
WhatsApp distils its pitch to a single line:
No account, no cost, no time limit.
Behind that slogan sits a significant architectural shift, because until now both ends of a WhatsApp call needed the application installed.
- Link-based access: The host creates a call link from the Calls tab and shares it wherever they like. No email invitation, no phone number exchange, no download for the recipient.
- Strict limits for outsiders: Guests can join one-to-one and group calls of up to 32 participants, share their screen, react with a thumbs-up or a heart and raise a hand. They cannot see other participants’ phone numbers, send messages or add anyone else to the call.
- Desktop browsers only: The official announcement references computer browsers and says nothing about mobile web, so joining from the phone of someone without WhatsApp should not be assumed.
- Gradual rollout: The option to generate guest links ships with the latest WhatsApp builds for Android and iOS, and is expected to reach more accounts “in the coming weeks.” No complete availability date or country list has been provided.
How a guest call actually works
The mechanics are deliberately minimal on the guest side. The host opens the Calls tab, taps the “+” icon, generates a link and shares it through any channel. The guest opens that link in their computer’s browser, enters a name and lands in a waiting room until the host admits them. Nothing to register, no phone number to surrender, nothing to install.
Call links themselves are not new — WhatsApp has offered them to ease group calls and video conferences since 2022. What has changed is who can walk through them. Independent testers spotted the guest-call feature under development in September.
Two details remain unresolved. The announcement does not say whether guest calls are voice, video or both; in the iOS beta examined during development, the host chose between voice and video when creating the link, but that was an unreleased build rather than the shipped one.
A waiting room as the security perimeter
Host approval is mandatory. WhatsApp cannot know who is behind a link — anyone who receives it, including anyone it was forwarded to, could try to slip in — so every guest must be admitted from the waiting room, and the host can eject a participant at any moment. Reporting that tracked the rollout describes that step as “not optional,” and notes the host can also end the call for everyone. During the September beta phase, the same source said an expelled guest would be unable to rejoin; the official announcement does not go into that level of detail.
That link-plus-a-name format is also the feature’s soft spot. A browser window that asks for nothing but a first name is trivial to imitate, so anyone receiving call links from unknown senders should apply the same caution they would to any suspicious URL.
On encryption, WhatsApp states only that calls are end-to-end encrypted for everyone. Independent reporting explains that the web client generates a unique identifier used to encrypt the call.
From guest chats to guest calls — and calendars next
Guest calls did not appear in isolation. In March 2026, WhatsApp ran a limited rollout of guest chats, letting users message people without an account. That format was narrower: text only, no file sharing, and conversations expired after 10 days of inactivity.
The next step is already announced. WhatsApp is preparing integrations with Google Calendar and Outlook for “later this year”: users will install an add-on, connect their account and attach a call link to a calendar invitation, with guests joining whether or not they have WhatsApp.
Viewed together, the pattern is unmistakable. WhatsApp is assembling, piece by piece, what it needs to compete in work meetings: a link, a waiting room, screen sharing, a calendar. The company itself frames these features as the latest in a year-long series of calling upgrades.
The strategic logic is that Meta does not need to persuade people who are already inside its ecosystem; it needs to strip away the excuses of those who refuse to sign up. If the experience holds up, today’s guest becomes tomorrow’s registered user.
The contentious part is the chosen form factor. Restricting entry to the desktop browser excludes precisely the most common use case for a quick call: the smartphone. Until that changes, guest calls will serve better for a meeting with a client or a relative living abroad than for replacing an ordinary phone call. The real test arrives with the calendar integrations. If a WhatsApp link starts landing in Outlook invitations as naturally as links from established video-conferencing tools, the debate over who owns informal meetings shifts accordingly. If it does not, guest calls will settle into place as one more convenience inside an app that already does almost everything.
