How do I change my backup email account for my iPhone? My daughter and I have been using the same one and I have apps that are not for me

Hi Mine2dew,

Thank you for participating in the Apple Support Communities. It looks like you came from the following support article: If your computer doesn't recognize your iPhone or iPad - Apple Support

If you are trying to separate your Apple ID accounts, you can try creating a separate Apple ID account for her using the link here: How to create a new Apple ID - Apple Support

If you would like to share specific apps and subscriptions, you can set up Family Sharing and invite her using the steps here: Set up Family Sharing - Apple Support

Have a great day.
