Zoom brings end-to-end encryption to its cloud phone service
during one-on-one calls. When it's on, E2EE will ensure calls are secure with cryptographic keys that only the calling and receiving devices can access. You'll be able to verify the E2EE status by sharing a security code with the other person.
At the moment, it's only possible to enable E2EE on Zoom Phone for calls between users on the same company Zoom account. They'll need to be on the Zoom Phone desktop or mobile app and switch off automatic call recording. Account owners or admins will need to enable E2EE via a web portal before their users can activate it on calls.
In addition, E2EE will soon be available in breakout rooms — smaller discussions that break off from group meetings. Each breakout room can have its own encryption key. Again, account owners or admins will need to enable E2EE for their users.
