To access an iCloud account, users may log in through the iCloud website using their Apple ID and password. This is done from both desktop and mobile devices.
To gain access to the benefits of iCloud, users must first sign up for iCloud and set it up on their devices. iCloud is set up from an iPhone, iPad, iPod Touch, Mac, PC or an Apple TV. Once an account is set up, data from all devices connected are kept in sync on the cloud, such as the iCloud Drive, Photos, Family Sharing, Find My iPhone/iPad/iPod Touch/Mac, Backup, Calendar, Bookmarks and Mail services.
