Zoom announced today that it will roll out end-to-end encryption (E2EE) to all users starting next week, as part of a 30-day technical preview.
To start using E2EE when joining new meetings during this rollout phase, meeting participants will need to join using the Zoom desktop client , mobile app, or from Zoom Rooms.

Users will know if their meeting is using E2EE if a green shield logo with a padlock appears in the upper left corner of the window.
“We’re excited to announce that starting next week, Zoom’s end-to-end encryption (E2EE) offering will be available as a technical preview, which means we’re asking for user feedback for the first 30 days,” Zoom’s Max Krohn said today.
“Zoom users – free and paid – around the world can host up to 200 participants in an E2EE meeting on Zoom, which provides them with increased privacy and security in Zoom sessions.
Zoom E2EE and its current drawbacks
All E2EE encryption keys are generated by the meeting participants' devices instead of Zoom's servers, thus making all data exchanged unreadable by Zoom or other third parties, except for each meeting participant.
To start using E2EE when participating in Zoom meetings, users must enable E2EE meetings at the account and select the E2EE option per meeting.
While E2EE provides users with improved security, privacy , and data protection in Zoom meetings, some features are limited when it is enabled.
Zoom estimates that the next phase of E2EE rollout will begin in 2021.
