Here's how to create a Hide My Email address on your iPhone:
1. Go to Settings > [your name] > iCloud > Hide My Email[1][3]
2. Tap "Create New Address" and follow the onscreen instructions to generate a unique, random email address[1][3]
3. You can optionally add a label for the address to remind you what it's used for, like "Newsletter Signup"[4]
4. The new address will automatically forward emails to your personal inbox while keeping your real email private[1][5]
5. When signing up for an app, choose "Sign in with Apple" and select "Hide My Email" to use the random address[1][4]
6. In Safari, tap an email field and choose "Hide My Email" to generate an address for that website[1][3]
7. In iOS 15.2 and later, you can also use Hide My Email in the Mail app by tapping the "From" field and selecting it[1][2]
So in summary, Hide My Email makes it easy to generate unique forwarding addresses right on your iPhone to keep your personal inbox private when signing up for apps, newsletters, and more. The addresses can be managed and deactivated at any time in your iCloud settings.
