Zoom has announced that it is adding end-to-end encryption (E2EE) to Zoom Phone, its VoIP collaboration service, as it aims to further enhance security.
According to a blog post (opens in new tab) by Zoom Head of Security Engineering, Max Krohn, video conferencing users can upgrade to E2EE “during conversations between users on the same Zoom account that take place through the Zoom client” using cryptographic keys known only to the devices at both ends of the phone call.
Zoom phone (opens in new tab) is not the only tool to get end-to-end encryption. Breakout Rooms will also have this feature soon. The changes will go largely unnoticed, with few changes in the experience of a breakout room outside of each room receiving its own, unique encryption key.

The option to do this upgrade can be found in the “More” section of any calling interface, but there are some requirements to make sure you can’t encrypt your call. First, the account administrator must enable the feature. The callers must also be on the same account, use the Zoom Phone desktop or mobile client, and have automatic call recording turned off.
In an effort to provide “adequate protection,” the company has already implemented data routing controls, in-product privacy notifications, and end-to-end encryption elsewhere.
The company says using end-to-end encryption in a conference room will be “the same experience” as a standard meeting, but will help protect private conversations and interactions outside the main conference room.
End-to-end encryption for both Zoom breakout rooms and conversations requires version 5.4.0 of the app which is available for Windows, macOS and Linux computers and iOS and Android mobile devices.
“Whether it’s E2EE for Zoom Phone and Breakout Rooms, our account theft protection tool or automatic updates – we’re committed to making security accessible to everyone,” Krohn wrote.
“These are just a handful of the easy-to-use tools you can use to protect your information while maintaining the flexible, reliable Zoom experience. Our frictionless, innovative design isn’t mutually exclusive with a strong security posture – in fact, they are one and the same.”
