Restrict account changes and volume controlKeep your child from messing with the account settings or volume on iPhone or iPad.
Parental Controls, also known as Restrictions, let you manage which features, apps, and content your kids can and can't access on your iPhone or iPad. This includes preventing any changes being made to your email, contacts, and calendar accounts, and to volume limits. Whether you're worried your young child will accidentally delete your accounts or your pre-teen might try to add a new account, you can quickly and easily lock it all in Settings.
