For sending mobile push notifications to Apple devices, Amazon Simple Notification Service (Amazon SNS) now enables token-based authentication. You may now choose between token-based (.p8 key file) and certificate-based (.p12 certificates) authentication when creating a new platform application in the Amazon SNS dashboard or API. 

Stateless communication between Amazon SNS and the Apple Push Notification service is enabled using token-based authentication (APNs). Because stateless communication does not require APNs to look up certificates, it is faster than certificate-based communication. You had to renew the certificate and the endpoint once a year while using .p12 certificates. You may now lessen your operational burden by eliminating the need for yearly renewals by employing a .p8 key file. Amazon SNS uses token-based authentication to deliver messages to mobile applications for platform applications produced with .p8 certificates. 

You can use token-based authentication for APNs endpoints in the following AWS regions where Amazon SNS supports mobile push notifications: US East (N. Virginia), US West (N. California), US West (Oregon), Asia Pacific (Mumbai), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Europe (Frankfurt), Europe (Ireland), and South America (São Paulo).
