A push certificate is an encrypted file generated by Apple that establishes trust between a third-party service like Jamf Pro and Apple Push Notification service (APNs). APNs is the medium through which Jamf Pro commands and information are sent to and from devices. Devices continuously listen to APNs for commands and send messages back to Jamf Pro through APNs after commands have been received.
Each push certificate is valid for one year and must be renewed using the same Apple Account that was used to generate it.
If you have a push certificate in .p12 format, you do not need to create a new one. You can simply upload the .p12 file to Jamf Pro following the instructions in this section.
You can also use Jamf Pro to renew your push certificate when needed.
Uploading a push certificate to Jamf Pro automatically enables the Enable push notifications setting in Jamf Pro's Security settings.
