iCloud: Use iCloud.com
You can view and change the information you have stored in iCloud by signing in to iCloud.com from a computer web browser and using the iCloud.com apps. To prevent anyone from viewing your information while you’re away from your computer, you can sign out.
Sign in to iCloud.com
Be sure you use a Mac or Windows web browser recommended in the Apple Support article System requirements for iCloud.
To avoid signing in the next time you visit iCloud.com, select “Keep me signed in.” If you return to iCloud.com within two weeks, you are not asked to sign in (except to use Find My iPhone, which continues to require your password). You stay signed in to iCloud.com even if you refresh your browser window, close the browser window where you are signed in to iCloud.com, or quit the web browser.
If you set up your Apple ID to require two-step verification, follow the onscreen instructions to verify your identity by entering a code sent to your 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 clicking it after entering your Apple ID.During two-step verification on iCloud.com, you can select the option Remember This Browser so that you won’t be asked to verify your identity using your trusted device the next time you sign in.
If you ever used your Apple ID to set up iCloud on your iOS device or Mac, you can use all the iCloud.com apps: Mail, Contacts, Calendar, Notes, Reminders, Photos, iCloud Drive, Find My iPhone, Pages, Numbers, Keynote, and Settings.
If you haven’t yet set up iCloud on your iOS device or Mac, you can still use Pages, Numbers, Keynote, and Settings on iCloud.com.
For troubleshooting tips, see If you have trouble signing in to iCloud.com.
Switch to a different iCloud.com app
After you sign in to iCloud.com and start using an app, you can easily switch to another app.
At the top of the iCloud.com window, click the name of the app you’re currently using, then click another app.
If you only see Pages, Numbers, Keynote, and Settings, your account just has access to iCloud web-only features. To see and use other iCloud features, set up iCloud on your iOS device or Mac.
Sign out of iCloud.com
If you’re signed in to iCloud.com from more than one browser, you can sign out from the browser you’re using now or all browsers.
Sign out from the browser you’re using now: Click your name at the top of the iCloud.com window, then choose Sign Out.
If you selected the option to remember this browser the last time you signed in using two-step verification, a dialog appears in which you can deselect that option and thus require two-step verification the next time you sign in.
If you didn’t select “Keep me signed in” when you signed in to iCloud.com, you can also sign out by quitting your browser app.
Sign out from every browser where you’re now signed in: Go to Settings on iCloud.com, click Data & Security, click Sign Out Everywhere, then click “Sign out of all browsers.”
