Earlier this year, Zoom announced plans to implement the real end-to-end encryption for calls after public scrutiny. The end-to-end encryption (E2EE) was meant for to paid users only, after sustained lobbying, the company will launch the feature to all.
This feature will require users to verify their identity using SMS-based Two-factor authentication (2FA). Zoom now plans to roll out E2EE on its platform starting next week.
Zoom has been using its own security, the AES 256-bit GCM encryption, to protect users’ privacy and security by ensuring safe transit of data while on calls. But, this was not ultimately the most secure standard hence the sustained lobbying from privacy advocates. E2EE is the widely accepted encryption standard.
E2EE encryption will generate unique keys for encrypting calls which will be stored on the device in use hence no chance for 3rd parties including Zoom to intercept ongoing calls.
This feature will be available as a “technical preview” next week, and for the next 30 days, the company will seek feedback from early adopters.
Next week’s release is one of the four phases in Zoom’s E2EE rollout timeline that will be concluded next year.
Meeting hosts and participants will have to update their respective clients to use the feature.
“You must join the meeting either from the Zoom desktop client, mobile app, or Zoom Rooms,” the company said in a blog post.
Additionally, Zoom users must enable E2EE meetings at the account level and opt-in to E2EE on a per-meeting basis.
And according to Zoom, all participants must have the setting enabled to join an E2EE meeting.
Under the imminent phase 1, E2EE will only apply to meetings with up to 200 participants.
Currently, Zoom Enterprise customers can host meetings with a maximum of 1000 participants.
You will know E2EE is turned on when you see a green shield logo in the upper left corner of their meeting screen with a padlock in the middle.
