Once a year, you will need to renew your Apple Push Notification (APNS) certificate with Apple. In order to renew your APNS certificate, you must use the same Apple ID that was used to create the certificate initially. If you do not renew this certificate before it expires, you will lose the ability to communicate with your enrolled devices and all devices must be re-enrolled.
If you are not sure which Apple ID you used to create your Push Certificate:
Apple will email you reminders starting at 30 days before expiration at the email address associated with your Apple ID used to create the APNS certificate originally.
Alternatively, you can match the "Common name" displayed within Jamf Now to the details on Apple's Push Certificates Portal.
1. Navigate to the Account section of Jamf Now.
2. Click on the Push Certificate tab.
3. You will see your Current Apple Push Certificate information. Reference the Common Name displayed at the top of this page. It begins with APSP....
4. Visit identity.apple.com and login with your Apple ID.
5. For any active Certificates, click on the blue "i" to view more info.
6. The "Subject DN" line will have details, including the unique APSP name for this certificate. Once you locate the string that matches the Common Name in your Jamf Now account, you know you've located the right certificate to renew. You can proceed with the steps listed above to renew.
Note: If no certificates match, sign in to Apple's Push Certificates portal with a different Apple ID until you locate the matching certificate to renew.
