Until now whenever I wanted to add Push notifications to my apps, I have followed the steps outlined in Erel's tutorial


This works great except that each year I need to update the APN certificates.

As the number of App I have in production increases, this is a bit of a b**lache.

It looks like there is another way which is to use an APN Authentication Key rather then APN Certificates.

What is the difference between APN Authentication Key and APN Certificates? As far as I can see:

Plus, it never expires!


Setting Up an APN Authication Key.

Step 1: Go to the Keys section of your apple Developer account and click on the blue Plus.

Step 2: Give the Key a name and select the "Apple Push Notification service (APN)" option. Click Continue.

Step3: On the next screen, Click Register

Step 4 : Download the key. Keep it safe!!!! Record the KeyID as you will need this later. (it is also in the filename, helpfully)

Step 5: Add the key to your firebase account under SETTINGS -> CLOUD MESSAGING ( the same place as the previous keys)

Step 6: Click on the Upload button and find the file you downloaded from Apple

The Key ID is from the Apple site, they helpfully include it in the filename of the downloaded file.
The Team ID is the ID of your Team in Apple, It normally appears in the top right of the Apple screen underneath your name.

Step 6: Click Upload

You're Done!

I found that this is a drop in replacement for the APN Certificates. Everything seems to be working fine.

Update: as @Marcos Alves identifed in this thread. https://www.b4x.com/android/forum/threads/problem-with-certificate.129709/ , It takes some minutes for the certificate to propagate so if you are replacing a live working certificate, be patient.

Do you use the same APN Auth Key for all your Apps? I noticed that you can only create two Keys and that the keys are not specific to the App ID so it seems like one would have no choice but to use the same key for several Apps/Projects.

Also, did you upload the same APN key for Development and Production?
