Zoom to offer full end-to-end encryption to all users

Zoom Video Communications Inc. will offer full end-to-end encryption to all users, free and paid, succumbing to pressure from members of Congress and the public who pushed the video-conferencing company to bolster privacy.

Those using the service at no charge will have to verify their phone numbers to get access to the strongest level of security, Zoom Chief Executive Officer Eric Yuan said Wednesday in a blog post.

End-to-end encryption makes it impossible for third parties to decipher communications, but will mean that participants cannot call into a Zoom meeting on a telephone line.

Note this will most likely be E2E encryption for audio, not video.

Also, how does E2E encryption work if they store copies of videos? So they have a copy of the encryption key, that defeats the purpose of E2E encryption.

This is from April: https://citizenlab.ca/2020/04/move-...look-at-the-confidentiality-of-zoom-meetings/

They use their own definition of E2E.
"When we use the phrase 'End to End' in our other literature, it is in reference to the connection being encrypted from Zoom end point to Zoom end point," the Zoom spokesperson wrote, apparently referring to Zoom servers as "end points" even though they sit between Zoom clients. "The content is not decrypted as it transfers across the Zoom cloud" through the networking between these machines.
