Starting later this year, new Sign in with Apple addresses, previously issued onprivaterelay.appleid.com, will be issued onprivate.icloud.com. Existing addresses onprivaterelay.appleid.comwill continue to work and forward mail to users without interruption.
After further consideration and reviewing community feedback, iCloud+ Hide My Email addresses will remain onicloud.com.
Developers with apps or websites that use Sign in with Apple should ensure that their account systems, email validation logic, and allowlists accept addresses on the newprivate.icloud.comdomain in addition to the existingprivaterelay.appleid.comdomain.
