Developed by Meta, this upcoming functionality eliminates the requirement for participants to install the app or register an account, positioning the messaging platform to compete directly with traditional video conferencing software.
As users seek seamless communication options, this product development bridges the gap between casual messaging apps and institutional meeting tools while maintaining platform security.

What Are the Core Mechanics of WhatsApp Guest Calling?
WhatsApp is developing a guest calling feature that allows individuals without a WhatsApp account to join voice and video calls using a secure browser link. The feature requires mandatory host approval for every non-account participant and maintains end-to-end encryption through unique browser-session identifiers.
Meta is engineering a product update that redefines how users connect on WhatsApp. According to recent reports detailing insights from WABetaInfo, the guest calling capability will enable hosts to create call links directly from the Calls tab. Participants without an active WhatsApp account can simply open the shared link in a browser and join through WhatsApp Web without downloading software or registering an account.
To ensure security, the architecture incorporates mandatory access controls. Before any guest enters a call, the host must manually approve the request. This verification applies to every participant joining without an account and cannot be disabled by the host. Once admitted, hosts retain full administrative authority, including the ability to approve or reject additional entry requests, remove participants, or terminate the call for all attendees.
WhatsApp Guest Calling vs. Guest Chats: Key Structural Differences
| Feature Aspect | WhatsApp Guest Calls | WhatsApp Guest Chats |
|---|---|---|
| Session Duration | Real-time; ends when the call finishes | Can remain active for up to 10 days without activity |
| Access Requirement | Secure browser link with mandatory manual host approval | Username reservation allowing communication without phone numbers |
| Account Requirement | None required for guests | None required for initial connection via usernames |
How WhatsApp Guest Calling Impacts Competition and Security
By introducing browser-based guest links, WhatsApp moves into territory traditionally dominated by enterprise tools like Zoom and Google Meet. For businesses that rely on WhatsApp as a primary communication channel with customers, the friction of requiring every client to have an active app installation has historically limited its use for formal group discussions. Guest access bridges this operational gap, potentially encouraging more participants to eventually sign up for accounts while streamlining immediate client outreach.
From a privacy perspective, Meta has designed these sessions to operate under default end-to-end encryption. WhatsApp Web generates a unique browser-session identifier to establish the secure encryption key for each guest. Unlike guest chat features introduced earlier in the year—which can remain active for up to ten days without activity—guest calls occur strictly in real time and conclude immediately when the call finishes. As development continues, market watchers and technology enthusiasts await official announcements regarding public beta testing and rollout timelines.

“Usernames are designed to give you control over who gets to see your phone number in the first place. It’s an optional feature; you choose your own username, you can change it or remove it, and it doesn’t have to match your handle or account name on any other app.” — Alice Newton-Rex
