Hello, 京理.
Hide My Email generates unique, random email addresses that automatically forward to your personal inbox. Each address is unique to you. You can read and respond directly to emails sent to these addresses and your personal email address is kept private.If you create an account with an app or visit a website that supports Sign in with Apple, you can choose to share your email address, if you're familiar with the app or website, or hide your email address, if you'd prefer more privacy. If you choose the Hide my Email option, only the app or website you created the account with can use this random email address to communicate with you. Learn more about Sign in with Apple. If you are not seeing the option on certain websites, it may be because Sign in with Apple is not supported on it.With an iCloud+ subscription, you can generate unique, random addresses from your iPhone, iPad, or iPod touch with iOS 15 or iPadOS 15 or later in any email field in Safari. You can also generate email addresses on-demand in the Settings app or on iCloud.com. This may be an option for you on the websites that don't support Sign in with Apple.
