iOS Token-based APNs

Apple has provided a new method (authentication token) for APNs.

Compared to the previous method (provider certificate), the certificate *.p12 expires every year.

Token-based *.p8 never expires.

• Establishing a Token-Based Connection to APNs
• Communicating with APNs

For clients

The only difference for the client is

1. Create an authentication token signing key on https://developer.apple.com/
2. Download the *.p8 and send it to the backend engineer.

For the backend

Many frameworks support *.p8.

For example:

Firebase
