iCloud: Set up iCloud
You set up iCloud on your devices by signing in and turning on the features you want to use on each device. Sign in on your iOS device or Mac first, and then you can sign in on your Windows computer and Apple TV. Before you can sign in on your Windows computer, you must first install iCloud for Windows.
If you don’t have an iOS device or a Mac, you can get iCloud web-only access to use Pages, Numbers, and Keynote for iCloud from your Mac or Windows web browser.
Set up iCloud on a device: Follow the instructions on the Set up iCloud website. When setting up iCloud, you sign in using your Apple ID. If you don’t have one, you can create one while signing in on an iOS device or a Mac.
Important: Be sure to use the same Apple ID for iCloud on your devices and on iCloud.com.
Get iCloud web-only access: Go to iCloud.com, then sign in using your Apple ID. If you don’t have one, click “Create one now” (below the Password field), then follow the onscreen instructions to create one. You can use it to sign in to iCloud.com and work with Pages, Numbers, and Keynote for iCloud.
