End to End Encryption (E2EE)

What is Zoom End to End Encryption?

 End-to-end (E2EE) encryption adds a layer of security for meetings where there is a need for enhanced privacy, or the data protection for your meetings.

When a host enables E2EE in a meeting, these features are disabled:

  • Join before host
  • Cloud recording
  • Live streaming
  • Live transcription
  • Breakout Rooms
  • Polling
  • Meeting reactions
  • 1:1 private chats

  • Users will not be able to join by telephone, SIP/H.323 devices, on-premise configurations, the Zoom web client, third-party clients leveraging the Zoom SDK, or Lync/Skype clients, as these endpoints cannot be encrypted end to end. 

All participants must join a meeting from a Zoom desktop client or mobile app. Joining from a web browser is not permitted.

  • Zoom desktop client
    • Windows: 5.4.0 or higher
    • macOS: 5.4.0 or higher
    • Linux: 5.4.0 or higher
  • Zoom mobile app
    • Android: 5.4.0 or higher
    • iOS: 5.4.0 or higher

How does it work?

In standard Zoom meetings, the Zoom servers encrypt transmission of the video and audio. If a meeting host uses E2EE, the keys for each Zoom meeting are generated by participants’ machines, not by Zoom’s servers. 

To enable E2EE for all your meetings (not recommended):

  1. Go to westernu.zoom.us and sign in
  2. Click Settings, then scroll down to Allow use of end-to-end encryption, click the toggle to enable it
  3. Under Default encryption type, check End-to-end encryption
  4. Click Save 

To enable E2EE for a meeting:

  1. Go to westernu.zoom.us and sign in
  2. Click Settings, then scroll down to Allow use of end-to-end encryption, click the toggle to enable it (defults to Enhanced encryption)
  3. Click Meetings, then click Schedule a Meeting 
  4. Under Encryption, select End-to-end encryption 
    Note: Because of the limitations of E2EE, Zoom recommends using Enhanced encryption as the default encryption type and using end-to-end encryption for meetings where additional protection is required.

 

Using E2EE for meetings:

Once you’ve joined the meeting, check for the green shield icon  in the upper left corner of the meeting window.

The meeting host can also read the security code aloud and the participants can verify that their codes match.
