Apple announced that starting later this year, new Sign in with Apple relay addresses will be issued on private.icloud.com instead of privaterelay.appleid.com, though existing addresses will continue to work. After community feedback, iCloud+ Hide My Email addresses will remain on icloud.com rather than migrating. Developers must update email validation logic and allowlists to accept the new private.icloud.com domain.

Why: If your app or SaaS uses Sign in with Apple, check your email validation regex and allowlists now—addresses on private.icloud.com will start appearing and will be rejected if your system only accepts privaterelay.appleid.com. This is a narrow but concrete breaking change for authentication flows.
