Client-side encrypted Google Meet calls now support external participants

Google has introduced support for external participants for client-side encrypted Google Meet calls, including users without a Google account. You need to turn on access for external participants and determine which identity provider the guest uses to join.

"Adding support for external participants means customers can collaborate with any of their stakeholders safe in the knowledge that only the meeting participants can decrypt the call media. This feature further extends the privacy and compliance capabilities of Google Meet and is the latest security enhancement, alongside encryption for in-meeting chat messages, co-host support, and the ability to join an encrypted meeting from a mobile device," Google wrote in a blog post.

To turn on client-side encryption for a meeting, go to a calendar event with Meet video conferencing, navigate to Settings > Security and select Add encryption'. It is worth noting that only directly invited participants can join client-side encrypted meetings.

To join encrypted calls, external users will have to validate their identity using a method supported by the Identity Provider. For instance, they can log in with an account from e.g. Google or Microsoft, or receive an email with a one-time password.

The new feature is rolling out to Rapid and Scheduled Release domains and may take up to 1-3 days to be fully visible. It will be available to select Google Workspace editions including Enterprise Plus and Education Standard and Plus.
