Auto Renew a Certificate

The Certificate Auto Renewal option renews an existing certificate automatically before it expires and without manual intervention. This ensures continuous security and avoids service disruptions due to expired certificates.

The auto renewal job will run once a day. If renewal triggers and fails, 5 additional attempts will be made once a day for 5 days to auto renew. Certificates that are expiring within 30 days or less can be auto renewed.

Auto renewal workflow:

  1. During certificate generation or manual renewal, set the Auto-renewal toggle to ON.
  2. Daily auto renewal job is triggered and scans certificates expiring in ≤30 days.

    If the renewal trigger fails, 5 additional attempts will be made once a day for 5 days to auto renew.

  3. A new certificate is created using the renewal configuration at the time of renewal.
  4. After renewal, a new renewal record will be created to persist the auto renewal settings on the new certificate.
