WhatsApp has initiated the rollout of two new functionalities to its web platform's beta testers: one-on-one voice and video calling, and a guest chat feature. These introductions aim to expand the web application's capabilities, previously focused on messaging, by offering direct call support and enabling communication with individuals who do not have a WhatsApp account.
These new features aim to significantly expand the utility of WhatsApp's web application, moving beyond traditional messaging to include direct call support and communication with non-WhatsApp users.
WhatsApp Web Voice and Video Calls
Rollout to Beta Users
WhatsApp Web has begun rolling out one-on-one voice and video calling support to users enrolled in its beta program. This functionality was previously exclusive to the platform's official desktop applications. The feature extends call capabilities to web browsers on various devices, including those running Linux. A broader public release is anticipated in the coming weeks.
Call Features and Encryption
Users can initiate voice and video calls directly from individual chats through dedicated call buttons. All calls are secured with end-to-end encryption, utilizing Signal's protocol. Video calls also include a screen sharing feature for enhanced collaboration.
Future Group Call Development
Group voice and video calls for WhatsApp Web remain under development, with no specific release timeline provided. When launched, group calls are expected to support up to 32 participants and may include features such as call links and scheduled calls.
Accessing the Beta Program
Users interested in accessing new features early can join the WhatsApp Web beta program. To do so, navigate to Settings > Help and Feedback and activate the "Join the Beta" switch. Enrollment in the beta program positions users to receive new features but does not guarantee immediate access.
WhatsApp Guest Chat Feature
Functionality Overview
WhatsApp is introducing a guest chat feature to a limited group of beta testers on iOS and the web, following its initial availability to Android beta testers in August. This feature allows WhatsApp users to initiate conversations with individuals who do not possess a WhatsApp account.
To use the feature, a WhatsApp user generates a unique chat link from the "Invite a friend" section and distributes it via SMS or other applications. When a recipient opens the link, a secure chat session is launched through WhatsApp Web.
Security and Participant Identification
Upon proceeding as a guest, WhatsApp Web generates a unique identifier to create an encryption key, ensuring guest chats are secured with end-to-end encryption. The conversation must be initiated by the guest, who is required to open the link, accept WhatsApp’s terms, enter a name, and then start the chat.
Any individual possessing the invite code can join the chat. In these sessions, guests are labeled with "(Guest)" alongside a disclaimer stating "Not registered with WhatsApp." This feature has been noted to potentially encourage new account creation.
Current Limitations and Availability
Currently, guest chats are subject to several limitations, including:
- No support for group chats
- No voice messages
- No attachments
- No stickers
- No GIFs
- No voice or video calls
Guest chat sessions are configured to expire after 10 days of inactivity. The feature is presently accessible to a restricted group of beta testers across iOS, Android, and web platforms, with no official timeline provided for a broader public release.
