Changing your iCloud name allows you to update the name associated with your Apple ID across all of your Apple devices and services. This can be useful if you’ve changed your name, want to use a different name for your Apple account, or if you’re experiencing any issues with your current name.
There are a few different ways to change your iCloud name. You can do it through the Apple ID website, through the Settings app on your iPhone or iPad, or through iTunes on your Mac or PC.
