Apple shifts new Sign in with Apple addresses to private.icloud.com domain

Apple has announced that new Sign in with Apple addresses will be issued on the private.icloud.com domain starting later this year. This marks a shift from the previous privaterelay.appleid.com domain, which has been used for the service since its inception.

The change is part of a broader update to the Private Email Relay Service. According to the announcement, existing addresses on the privaterelay.appleid.com domain will continue to function and forward mail to users without interruption. This creates a dual-domain period where both addresses remain valid for current users.

In a separate decision, Apple confirmed that iCloud+ Hide My Email addresses will remain on the icloud.com domain. The company stated this decision followed further consideration and a review of community feedback, distinguishing these addresses from the Sign in with Apple service.

Developers using Sign in with Apple in their apps or websites are advised to make specific technical adjustments. They must ensure that their account systems, email validation logic, and allowlists accept addresses on the new private.icloud.com domain.

Crucially, developers should accept the new domain in addition to the existing privaterelay.appleid.com domain. This ensures that both new and legacy addresses are recognised by third-party platforms without disruption to user access.

The announcement was published via Apple Developer News, providing the official timeline and technical guidance for the transition. While the exact date for the switch to the new domain is not specified, the change is scheduled to occur later in the current year.
