To get started making the necessary changes to your account on an iOS device, go into the Settings app and scroll down until you see iCloud. In that case, you’ll need to change the email address associated with your Apple ID. The email address associated with the Apple ID you are using for iCloud is no longer a valid, active email address.That’s not an ideal situation if you prefer to keep your data separate. If you are using the same Apple ID as a family member for iCloud, your contacts, calendars, and other content could be merged, or you might be getting each other’s iMessages and FaceTime calls.First off, before we begin and actually discuss how to safely delete or change an iCloud account, we should discuss the different scenarios as to why you might need to delete or change your iCloud account off of your device.
