PSA: Apps using Apple’s Game Center must be updated with a new authentication certificate

Apple today told developers they need to update their games to include Game Center, Apple’s gaming platform that allows users to add and challenge friends online. The company says the adoption of a new authentication certificate will become mandatory for these applications.

In a new post on the Apple Developer Website, Apple has indicated that the new certificate is used for Game Center server-based verification. As of August 4, 2021, the new certificate will be required for all games available on the App Store integrated with Game Center.

If you are a developer and your game offers Game Center features, make sure it uses the current “publicKeyUrl”, which redirects to the latest certificate available. Otherwise, your app must be updated to maintain Game Center integration after August 4.

From August 4, 2021, a new certificate for Game Center Server Verification will be available through the publicKeyUrl. The old certificate will no longer be available after this date. As a reminder, make sure that your application retrieves and always uses the publicKeyUrl value so that it automatically uses the new certificate. If your application caches the certificate or hardcodes the certificate URL, an update will be required.
