Advanced Encryption for Chat Follow

Overview

Advanced encrypted chat will securely send chat messages between Zoom users. Encrypted messaging encrypts all chat messages using TLS 1.2 with Advanced Encryption Standard (AES) 256-bit algorithm.

If advanced encrypted chat is enabled, users can still send files, pictures, emojis, and screenshots. However, they will not be able to use the integrated GIPHY library, edit sent messages, or search chat message history. In Chat History on the Zoom Web Portal, account owners and admins will be able to see chat participants and the date and time of the last message sent, but they will not be able to read chat messages.
