Use iCloud.com
You can use iCloud from anywhere by signing in to iCloud.com from a web browser recommended in the Apple Support article System requirements for iCloud.
Note: Not all iCloud features are available on iCloud.com in an iPad browser. Sign in to iCloud.com using a Mac or Windows browser to access more features.
Sign in to iCloud.com
Go to iCloud.com, then sign in with the same Apple ID you used to set up iCloud.
If you’re already signed in to your device with your Apple ID and your device has Touch ID or Face ID, you can use it to sign in to iCloud.com.
Note: If you have web-only access to iCloud.com and you are on an iPad, you only see Contacts, iCloud Drive, and Notes. To learn more about web-only access, see the Apple Support article Web-only access to iCloud.
For troubleshooting tips, see Trouble signing in to iCloud.com.
Sign in to iCloud.com using two-factor authentication or two-step verification
For additional security, you can set up your Apple ID to require two-factor authentication or two-step verification.
Go to iCloud.com, then sign in with your Apple ID (the one you use with iCloud).
Follow the onscreen instructions to verify your identity by entering a code sent to a trusted device.
You must verify your identity this way to use any web app except Find My iPhone. You can use Find My iPhone by tapping it after entering your Apple ID.
Note: During two-factor authentication or two-step verification on iCloud.com, you can choose to trust the browser so that you won’t be asked to verify your identity the next time you sign in.
See the Apple Support articles Two-factor authentication for Apple ID and Two-step verification for Apple ID.
Switch to a different iCloud.com feature
At the top of the iCloud.com window, tap the name of the feature you’re currently using, then tap another feature.
If you have web-only access to iCloud.com and you are on an iPad, you only see Contacts, iCloud Drive, and Notes. To see and use other iCloud features, set up iCloud on your iOS device, iPadOS device, or Mac.
Sign out of iCloud.com
Do one of the following:
Sign out from the browser you’re using now: Tap your name at the top of the iCloud.com window, then choose Sign Out.
Sign out from every browser where you’re currently signed in: Go to Settings on iCloud.com, tap Sign Out Of All Browsers (in the Advanced section), then tap Sign Out.
