If I family share my iCloud will my family have access to my icloud
When sharing iCloud backup space with family, what do family members have access to?
iPhone 12 Pro Max, iOS 16
They only have access to their own data. For information about sharing iCloud Storage see the following from: Share iCloud+ with your family - Apple Support
When you share an iCloud+ subscription, everyone in the family group uses their own account. That way your photos, documents, and other information stay private, even though you're sharing access to the service. You simply share the features and space available in iCloud+ with your family members, so you only have one plan to manage.
