Users who have chosen to register with their hidden Apple ID might see a random email address under their account’s profile, which was provided by Apple for registration.
The hidden ID option means Apple does not disclose the user’s actual email address to Any.do, but instead provides a randomly generated ID in the following format: XXXXXX@privaterelay.apple.com.
In order to change this setting and register with the actual email associated with your Apple ID, you may simply switch from hidden to visible in your Apple ID Settings:
- On your mobile or Mac device, open your Apple ID.
- Go to Password & Security.
- Choose “stop using apple id”.
Next time you try to sign up with Apple, you will have the option to select ‘hidden’ or ‘show my email’.
