When you select "Hide my email" during the sign-up process with Apple, a randomly generated email address (e.g., email@example.com) is created for you. This generated email address is associated with the email address used for your Apple ID. Here's how you can find it:
If you are not logged in:
- Tap "Continue with Apple" to log in.
If you are already logged in:
- Tap "Profile".
- Go to "Settings".
- Select "Edit profile".
- Scroll down and locate the "Email" section.
If you decide that you want to switch from using Apple login to an email address login, you can follow the steps outlined here.
