Overview
- Apple announced in a developer notice on Monday, June 15 that new relay addresses for Sign in with Apple and iCloud+ Hide My Email will be issued on private.icloud.com.
- Apple says existing aliases on privaterelay.appleid.com and icloud.com will continue to forward mail and keep working after the switch.
- Developers must update account validation, allowlists and signup logic while email providers must change domain-based filtering, suppression lists and routing rules before the rollout.
- Security reporters and privacy advocates warn the new private.icloud.com subdomain creates a clear technical marker that could let apps and websites detect and block anonymized Hide My Email aliases.
- The move standardizes Apple’s relay infrastructure and may sharpen a trade-off between platform anti-abuse controls and user anonymity, a debate that observers say Apple has not publicly explained.
