A vulnerability has been discovered in Apple's 'Hide My Email' feature, which is intended to protect users' real email addresses by generating unique, random addresses for online use. The flaw allows certain individuals to uncover users' actual email addresses. Although reported to Apple in June 2025, the issue remains unresolved as of July 2026, with Apple stating they are still investigating. Users are advised not to rely solely on this feature for privacy until the issue is fixed.
Apple plans to make the 'Hide My Email' feature less effective by changing the generated addresses to a new domain, which may lead to acceptance issues in some apps and websites. Overall, users are encouraged to use different email addresses for different services to enhance privacy.
