Downloading the public key for Linux

In February 2026, Zoom is retiring the current key pair used to sign the Zoom desktop app for Linux, which customers can use to validate the Zoom desktop app. Users must download the new public key before attempting to upgrade to version 6.7.5, otherwise they will be unable to install this update. Prior versions (before 6.7.5) will not be impacted.

For versions 6.7.5 and higher, the Linux and Docker GPG signature thumbprint will change from "Key fingerprint: AE44 6BAB 33EA 9862 AA29 FC3D DDEO E622 2047 091F" to "Key fingerprint: 84C3 65D6 CC9A 4886 CA92 6BCC 4F21 9739 9706 AC24".
