When you enter a new password in Safari, you’ve probably seen iCloud Keychain ask if you would like it to save it for use across all your devices. So long as you are running iOS 7.0.3 or later or OS X Mavericks 10.9 or later, iCloud Keychain will store the following items securely in iCloud. Once secured in iCloud Keychain, you will be able to access all these items securely from any Apple system logged into your Apple ID.
- Safari website usernames and passwords
- Credit card information
- Wi-Fi network information
- Ensure Mail, Contacts, Calendar and Messages are synced across all your devices
- Protect, access and deploy your LinkedIn, Twitter and other Internet account logins and passwords.
