WhatsApp Opens Calls to Guests With No Account Needed
WhatsApp has launched guest calling, which lets an account holder invite anyone into a call with a link and no sign-up on the guest side. The host generates the link inside WhatsApp and shares it outward. The guest opens it to join. The Verge
Joining does not require the mobile app. Guests join through WhatsApp on the web, which added call support earlier in 2026. Starting a call still requires a WhatsApp account. Signed-in users host, others attend.
Guests can do more than listen and watch. They can raise a hand, share a screen, and send emoji reactions. The call remains end-to-end encrypted, which means only the people on the call can hear or see its contents, including the guest connection.
Admission is controlled. Every guest waits in a waiting room until the host gives explicit approval. Hosts can remove a guest at any point during the call.
Limits apply inside the call as well. Guests cannot see other participants' phone numbers. They cannot send messages in the call. They cannot add other people directly. The permissions are narrow: join, speak, present, react, leave.
Meta also plans Google and Outlook calendar integrations for WhatsApp calls later in 2026. Users who install a WhatsApp plug-in and connect their account will be able to attach a WhatsApp call link to calendar invites.
WhatsApp described the change in a post titled "Now You Can Invite Anyone to a WhatsApp Call." The company states guest calls carry no cost and no time limit. WhatsApp
The broader context here is where WhatsApp placed the trust boundary. Identity is verified at the host, entry is enforced at admission, and guests run on least privilege, a term engineers use for giving only the minimum access needed. That keeps the call usable for outsiders without adding them to the contact graph or exposing identifiers that normally travel with a WhatsApp identity. It fits the calls that create the most friction today, with contractors, candidates, vendors, support cases, or family members on unfamiliar devices, where the failure was rarely media quality but setup, with installs, accounts, and permissions to sort out.
In my view, the trade-off to watch is unauthenticated endpoints inside an encrypted session. End-to-end encryption protects the audio and video from intermediaries, but it does not confirm who clicked the link. WhatsApp leaves that job to the host, through approval, removal, and shielding of phone numbers. For informal chats and most work coordination, that seems a reasonable split, though sensitive talks will need discipline around link sharing and admission, since a forwarded link is only as reliable as the approval that follows it. Having watched my children adopt the tools that opened in one click and skip the ones that needed a download, I expect the upside here is real, with less preamble bringing more people into secure calls.
