What is an APNs Cert?It has probably been a year since you’ve seen those words so I’ll remind you. The APNs Certificate is the certificate that you created in order to enroll devices. It was created using an Apple ID that we recommended be a generic company ID versus a personal Apple ID because it has to be renewed every year.
How to know what account was used to create the certificateWe recommend searching through your emails as Apple sends 4 notifications to the email associated with the Apple ID. Apple sends notices according to this schedule: when the certificate is created, 30 days before expiration, 10 days before expiration, and a Final Notice a day before expiration. Search your email for the following subject lines:
- Apple Push Notification Service certificate created
- 30 day notification: Apple Push Notification Service certificate expiration
- 10 day notification: Apple Push Notification Service certificate expiration
- Final notice-Tomorrow: Apple Push Notification Service certificate expiration
