Zoom adds end-to-end encryption for breakout rooms

Zoom is adding end-to-end encryption (E2EE) settings to more of its services.

Account owners and admins can enable end-to-end encryption to allow users to switch their calls to E2EE when additional protection is needed.

Using Zoom Phone E2EE requires caller and callee to be part of the same Zoom account, to join from the Zoom desktop or mobile client and automatic call recording to be disabled or the user is allowed to pause automatic call recording if it is enabled.

For Zoom Phone calls, users can add E2EE during a call by selecting "more" and hitting the option for the higher level of encryption. When enabled, the call will be encrypted using cryptographic keys known only to the devices that belong to the caller and the receiver. This can also be verified with special E2EE status in the form of a security code the participants can share with one another.

However, to enable E2EE a users will need to have E2EE turned on in the web portal and both callers will need to be on the same Zoom account. Both callers will also have to use the Zoom Phone desktop or mobile client and neither caller can record the call - automatic call recording will also have to be turned off.

Although other Zoom services previously had end to end encryption options, these protections did not extend to Breakout Rooms. Before this change, creating a meeting and attempting to set it to E2EE would automatically disable the Breakout Rooms feature. To extend the encryption to Breakout Rooms, each breakout will have its own unique encryption key. The feature is not live yet, but is coming soon.
