When does my certificate get renewed?
App Service certificates are valid for one year. If Auto Renew is on for an ASC then it will be renewed automatically before it expires and just like ReKey operation, the linked App Service Apps will be moved to the new certificate. You can change this setting by clicking on ‘Auto Renew Settings’ which is on by default. You can also manually renew a certificate by clicking on Manual Renew irrespective of the current Auto Renew setting if the certificate expiration is within 90 days.How can I Rekey and/or ReSync my app service certificate?
In order to stay compliant, many web companies need to rotate their certificates periodically. Also if a customer believes that his certificate has been compromised then he should rotate the certificate as soon as possible to minimize likelihood of the stolen certificate being used for malicious purposes. Traditionally, this requires obtaining a new certificate from the CA which is as complicated as buying a new one. Once a new certificate is created, you need to update all App Service Apps one by one manually. With ASC, we support one click ReKey. ASC allows you to ReKey a certificate unlimited number of times during its lifetime for free. Using Rekey and Sync option in the portal : This blade displays the current sync state. You can see the thumbprint of ASC along with the thumbprints of all App Service linked certificates. When these certificates are in sync, all thumbprints will match and when they are out of sync, one or more linked certificate thumbprints will be different from the ASC thumbprint. In order to rotate the certificate, click ReKey at the top. The ASC status will move to Rekey Certificate which may take 5-10 minutes. You dont have to click on Sync since a background task runs every 8 hours to sync the changes in the certificate. To force a sync , you can click on the Sync button .
