Apple to change Hide My Email domain, potentially reducing effectiveness of privacy feature
Tags Security · Consumer · Privacy
Apple plans to migrate anonymously generated email addresses from their current domain to a different domain in the coming weeks, a change that security researchers say could make the Hide My Email feature less effective. The feature, which creates random email aliases to protect users' real addresses, currently operates on a dedicated domain that some services have learned to identify and block. The domain change may disrupt existing alias configurations and could affect how third-party services handle emails from Apple-generated addresses.
Technical significance
Hide My Email is one of the most widely deployed consumer privacy tools, with millions of Apple users relying on it to manage email exposure. A domain change could break existing alias-to-service mappings and may allow services that previously blocked Apple aliases to develop new detection methods. For privacy-focused users, this highlights the fragility of privacy features that depend on infrastructure-level implementations rather than protocol-level standards.
