How to renew your Apple Push Certificate

The Apple Push Certificate, which is required to establish a secure connection between the Cortado administration portal and your users' iOS/iPadOS devices, is valid for one year. It must therefore be renewed regularly in the Apple Push Certificates Portal.


This How To explains the steps you need to take to renew your Apple Push certificate.


Open the Cortado administration portal and select Administration→ Settings→ Apple Push Certificate

Your Apple Push certificate is valid for one year (arrow in illus.). If the certificate has expired, you must renew it.

Note! Be sure to use the same Apple ID that you used to create your Apple Push certificate a year ago. If no certificate is available, you have probably signed in with the wrong Apple ID.

  • Use the serial number of the certificate to check whether it is the certificate to be renewed.
  • You can find the serial number (upper arrow in illus.) by clicking on the info button (lower arrow in illus.).

Caution! To renew the certificate, do not use the "Create a certificate" button but the "Renew" button. Otherwise you will generate a new certificate and all users will have to register their devices again.
