Using End-to-End Encryption (E2EE) during a Zoom Phone call
When End-to-end encryption (E2EE) is enabled by an account owner or admin for the account, this feature adds an extra layer of privacy to phone calls occurring over Zoom. You will be able to quickly switch your calls to be encrypted when necessary, and if your calls are automatically recorded, you will see an option to stop the recording to make the switch if you are allowed to stop your recording.
Note: Users can enable post-quantum end-to-end encryption (PQ-E2EE) for Zoom Phone calls. When enabled, users are notified that their call is Post quantum end-to-end encrypted. As users update their Zoom desktop and mobile app to version 6.6.0 or higher, all end-to-end encrypted calls will start leveraging our latest post-quantum end-to-end encryption protocol. If PQ E2EE is unsupported by any participant's device, the call will default to standard end-to-end encryption (E2EE) when enabled. PQ E2EE in Zoom Phone is designed to withstand the threat of an adversary who can capture encrypted network traffic, hoping to acquire a quantum computer in the future and use it to decrypt the captured data. PQ E2EE offers the same security property as standard end-to-end encryption (E2EE), namely that the call is encrypted using cryptographic keys known only to the devices of the caller and receiver.
Caller and callee are in the same Zoom account with Automatic Call Recording disabled Note: If Automatic Call Recording is enabled, the admin must allow the user to stop recording for E2EE to work.
