Apple Unifies ‘Sign in with Apple’ and ‘Hide My Email’ Domains

Apple is set to streamline its email services by consolidating the domains used for ‘Sign in with Apple’ and ‘Hide My Email’ under a single domain: private.icloud.com. This change is scheduled to take effect later this summer.

Currently, ‘Sign in with Apple’ generates email addresses ending with privaterelay.appleid.com, while ‘Hide My Email’ uses addresses ending with icloud.com. With the upcoming update, both services will issue email addresses under the unified private.icloud.com domain.

For end-users, this transition is designed to be seamless. Existing email addresses associated with the previous domains will continue to function without interruption, as Apple will ensure that emails sent to these addresses are properly forwarded.

However, developers and email service providers need to take proactive steps to accommodate this change. Apple has advised developers to update their account systems, email validation processes, and allowlists to recognize and accept email addresses from the new private.icloud.com domain. Similarly, email service providers should adjust their domain-based filtering, suppression lists, and routing rules to include this new domain.

Failure to make these updates could result in disruptions, such as users being unable to sign in to apps or services using ‘Sign in with Apple’ or experiencing issues with email forwarding through ‘Hide My Email’.

Apple’s decision to unify these domains aims to simplify its email services and enhance user privacy. By consolidating under a single domain, Apple can more effectively manage and secure the email addresses generated by these services.

In summary, while this domain consolidation is a positive step towards streamlined and secure email services, it necessitates prompt action from developers and email service providers to ensure a smooth transition and maintain uninterrupted service for users.
