Mark the Revoke this client certificate check box to confirm that the certificate should be revoked, and
then click the Revoke Certificate button.
After the certificate has been revoked, future checks of the certificate’s validity using OCSP or CRL will
indicate that the certificate is no longer valid.
Due to the way in which certificate revocation lists work, a certificate cannot be un-revoked. A new certificate must
be issued if a certificate is revoked in error.
Revoking a device’s certificate will cause the device to be unable to authenticate. It will not prevent it from being re-
provisioned. If you wish to deny access to a device, use the Manage Access link in the device's row on the
Management and Control >View by Device form.
l Delete certificate—Removes the certificate from the list. Trusted certificates that were imported into
Onboard may be deleted at any time after import. For all other certificates, this option is only available if the
data retention policy is configured to permit the certificate’s deletion.
