Previously issued on privaterelay.appleid.com, new addresses will now be created under private.icloud.com. Existing addresses will continue to function without interruption. This change will take effect later this year. ## Impact on Current Users Email addresses currently using privaterelay.appleid.com will keep working seamlessly. Apple confirmed users don't need to take any action for their existing accounts. The iCloud+ Hide My Email feature will remain on icloud.com as before. ## Developer Advisory Apple is urging app and website developers to support the new domain. Developers must update their account systems, email validation logic, and allowlists to accept private.icloud.com addresses. Failure to implement these changes might cause login issues for users. ## Reasons Behind the Change Community feedback and technical evaluations influenced Apple's decision. The company is making infrastructure changes to enhance user privacy. The new domain structure will allow for improved security measures and more efficient service management. ## About Email Relay Service Sign in with Apple lets users register for apps without sharing personal email addresses. The system generates random email addresses that forward messages to users' real inboxes. This protects users from spam and enhances their privacy. ## Developer Documentation Apple has published detailed documentation to facilitate the transition. The materials explain how to integrate the new domain and test it in development environments. The company recommends developers implement these changes promptly. ## User Experience Implications The domain change isn't expected to create noticeable differences for end users. The system will continue operating seamlessly in the background. However, if developers don't make necessary updates, users might encounter login problems. ## Apple's Privacy Strategy This change aligns with Apple's privacy-first approach. The company has introduced features like App Tracking Transparency and Mail Privacy Protection in recent years. The domain shift represents another infrastructure improvement supporting user data protection. ## Sources covering this story - https://developer.apple.com/news/?id=1ptvdtcm — --- _Summary written by Brifing from the original reporting.
