change email

Hi there yoav272,

Thank you for posting to Apple Support Communities.

Your Apple ID email is the email address that Apple Music is associated with. If you want to change your Apple ID, you'll need to sign out of all Apple services and devices that use your Apple ID.

That should help. Let us know if you have any questions.

Take care.

Hey there yoav272, 

The Family Sharing organizer will not have access to all information and activity on your device. You can learn more about what is sharable and not shared below.

What types of content can I share with my family?   

Have a good one!
