Zoom announced today that it will roll out end-to-end encryption (E2EE) for all users starting next week, as part of a 30-day technical preview.

To start using E2EE when joining new meetings during this roll out phase, meeting participants will have to join using the Zoom desktop client, mobile app, or from Zoom Rooms.

“We announced in May our plans to build an end-to-end-encrypted meeting option into our platform, on top of Zoom’s already strong encryption and advanced security features. We’re pleased to roll out Phase 1 of 4 of our E2EE offering, which provides a robust protection to help prevent the interception of decryption keys that could be used to monitor meeting content.”

All E2EE encryption keys are generated by meeting participants’ machines instead of Zoom’s own servers, thus making all exchanged data indecipherable by Zoom or other third parties, with the exception of each meeting participant.
