WhatsApp Now Lets Guests Join Calls Without an Account — Encrypted, by Link, No App Required

MENLO PARK THURSDAY, OCTOBER 15, 2026

Every family has one: the person who will happily join the video call but flatly refuses to install another app. WhatsApp just removed their last excuse. In an official announcement, Meta's WhatsApp introduced guest calling — a feature that lets anyone join a WhatsApp audio or video call through a shared link, even if they do not have a WhatsApp account at all. Gadgets 360 and 9to5Mac both covered the launch, and the details line up cleanly with WhatsApp's own post: the calls are free, end-to-end encrypted, and carry no time limits.

This is a bigger change than it might look on a changelog. WhatsApp has spent its entire life as a walled garden keyed to a phone number and an installed app. Guest calling opens a door in that wall — carefully, with the host standing at it — and points WhatsApp directly at the territory of Zoom, Google Meet and Microsoft Teams, where joining by link, account or no account, has been the whole pitch for years.

How guest calling works

The mechanics, per WhatsApp's announcement, are simple. A WhatsApp user opens the Calls tab, taps the "+" icon, creates a call link, and sends it to whoever they want to talk to — the company suggests colleagues, classmates or a tutor. The guest opens the link in a computer browser, types in their name, and lands in a waiting room. Guests can join one-to-one calls and group calls with up to 32 people, but only once the host admits them. Only people with a WhatsApp account can create a call link, so the feature widens who can attend a call without widening who can start one.

Inside the call, guests are not second-class citizens — but they are supervised ones. WhatsApp said guests can share their computer screen, react with a thumbs-up or heart emoji, and raise a hand to jump in, which covers most of what a tutor, a manager or a grandparent actually needs to do on a call. What guests cannot do is equally deliberate: they cannot see other participants' phone numbers, send messages, or add anyone else to the call. And the host's authority is absolute — a guest can be removed at any time.

The privacy design is the point

That combination — open door, strict host, hidden numbers — is clearly engineered to answer the obvious objection before it is raised. Letting strangers-by-link into an encrypted call sounds risky until you look at the controls: nobody enters without explicit host approval, guests are firewalled from the contact information that makes WhatsApp accounts valuable to scrapers and spammers, and the encryption promise stays intact. WhatsApp described the feature as free, end-to-end encrypted calls for everyone with no time limits — no abrupt cutoffs, no scrambling to restart a call that hit a cap.

The waiting room deserves a word of praise, too. It converts the call link from a skeleton key into a doorbell. Anyone who has watched a meeting link escape into the wild — forwarded once too often, posted somewhere public — knows the difference matters. With guest calling, a leaked link gets an unwanted visitor as far as a lobby, where the host can simply never let them in. That is the right default, and it is good to see WhatsApp choose it rather than the frictionless-but-riskier alternative.

Calendars are next

WhatsApp also announced that calendar integrations are coming later this year. Per the announcement, covered by 9to5Mac and FoneArena, users will be able to install a WhatsApp plugin, connect their account, and create a WhatsApp call link directly from a Google Calendar or Outlook event, so the link travels inside the invitation itself. Everyone invited can then join with or without a WhatsApp account.

That second piece is what turns guest calling from a handy consumer feature into a genuine workplace play. The reason Zoom and Meet links colonized professional life was never call quality — it was the calendar. The meeting exists in the calendar, the link lives in the invite, and joining is one tap at the appointed hour. By moving into Google and Outlook calendars, WhatsApp is asking to be scheduled the way its rivals are scheduled, by the enormous number of teams and small businesses that already coordinate in WhatsApp chats all day and then leave the app to actually hold the meeting.

Why this matters beyond one feature

Step back and the strategy is plain. WhatsApp already owns the group chat for much of the world — family threads, school parent groups, neighbourhood associations, small-business customer lists. What it has historically not owned is the formal call: the scheduled, link-based, anyone-can-join meeting. Guest calling attacks exactly that gap, and it does so using WhatsApp's two structural advantages: ubiquity (someone in almost every group already has the app and can host) and an encryption reputation its meeting rivals mostly do not match.

There are honest limits to note. Guests join from a computer browser, per the announcement — the phone-only relative is still out of luck until they find a laptop. Hosts must have accounts, and guests get a deliberately trimmed feature set. And WhatsApp is, as more than one outlet noted, catching up here rather than pioneering: link-based guest joining has been standard at its rivals for years. But catch-up moves by a platform of WhatsApp's scale have a way of becoming the default overnight. The relative who refuses to install the app can now join Sunday's call from the browser. Resistance, as of this week, is futile — and, for once, end-to-end encrypted.
