iCloud: Use iCloud.com apps
You can access your iCloud information using a computer web browser instead of using apps on your iOS device, Mac, or Windows computer. You go to iCloud.com, sign in, and then use the iCloud.com web apps: Mail, Contacts, Calendar, Notes, Reminders, iCloud Drive, Find My iPhone, Pages, Numbers, Keynote, and Settings.
You can access your iCloud information using a computer web browser instead of using apps on your iOS device, Mac, or Windows computer. You go to iCloud.com, sign in, and then use the iCloud.com web apps: Mail, Contacts, Calendar, Notes, Reminders, Photos, iCloud Drive, Find My iPhone, Pages, Numbers, Keynote, and Settings.
To prevent anyone from accessing your iCloud information on iCloud.com (such as your email) while you’re away from your computer, you can sign out. If you’re now signed in from more than one browser, you can sign out from all browsers at once.
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.
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.
During two-step verification on iCloud.com, you can turn on 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.
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.
If you select “Keep me signed in,” then anytime 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 into iCloud.com even if you refresh your browser window, close the browser window where you are signed into iCloud, or quit the web browser.

Switch to a different iCloud.com app
After you sign in to iCloud.com, you can easily switch between apps.
At the top of the iCloud.com window, click the name of the app you’re currently using, then click another app.
Sign out of iCloud.com
To sign out from the browser you’re using now, click your account name at the top of the iCloud.com window, then choose Sign Out.
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.
To sign out from every browser where you’re now signed in, click your account name at the top of the iCloud.com window, choose Account Settings, click Advanced, then click Sign Out of All Browsers.
