Communicate with APNs using authentication tokens
You can use one APNs signing key to authenticate tokens for multiple apps. The signing key works for both the development and production environments. The signing key doesn’t expire, but can be revoked.
Then get the key identifier to create a JSON Web Token (JWT) that you’ll use to communicate with the capabilities you enabled. To learn more, read Communicating with APNs in the Local and Remote Notification Programming Guide.
