End-To-End Encrypted Chat Follow

Overview

End-to-end 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 End-to-end 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. 

Prerequisites

  • Zoom Windows or Mac Version 4.1.8826.0925 or higher
  • iOS Version 4.1.8855.0925 or higher
  • Android Version 4.1.8860.0925 or higher

Note that some older versions of Zoom, including Windows and Mac version 3.5.37712.0111 or higher, iOS version 3.5.37749.0111 or higher, and Android version 3.5. 37712.0111, support End-to-end encrypted chats, but will not have full functionality. 

Enabling End-to-end encrypted chat

To enable the End-to-end encrypted chat feature for all members of your organization:

  1. Sign into the Zoom web portal as an administrator with the privilege to edit IM Groups and click IM Management.
  2. Click the IM Settings tab at the top of the page.
  3. Navigate to the Enable end-to-end chat encryption option and verify that the setting is enabled.
    If the setting is disabled, click the status toggle to enable it. If a verification dialog displays, choose Turn On to verify the change.

Chats will display a lock in the text box. 


 

If a user receives an encrypted chat message, it will not display the text until they open Zoom. Notifications will display a message that they have received an encrypted chat.
