Zoom will be making the new Service Provider certificate available on November 5, 2025, ahead of the expiration of the previously issued 2024/2025 certificate on Sunday, December 21, 2025.
No action is required for customers using an identity provider (IDP) or configuration that supports dynamic metadata refresh, as your IDP will automatically download the latest Zoom certificate and rotate it into your account’s configuration starting Wednesday, November 5, 2025.
If automatic update is disabled or your IDP does not support automatic certificate rotation, your organization will need to manually rotate the certificate by December 21, 2025. If the certificate has not been rotated by then, your organization will be unable to utilize SSO services until the certificate has been updated.
Note: if the SP Certificate box is not on your SSO configuration page, no action is required to rotate to the new certificate. Posted on
