OS X Mavericks: Set up iCloud Keychain
iCloud Keychain keeps the following account information up to date across your Mac computers with OS X v10.9 or later and iOS devices with iOS 7.0.3 or later:
Website account names and passwords that Safari autofills for you
Credit card numbers and expiration dates that Safari autofills for you
Most Wi-Fi network names and passwords
iCloud Keychain also keeps account names, passwords, and settings that you add to Internet Accounts preferences up to date on your Mac computers.
Passwords and credit card information are encrypted in your OS X keychain and your iCloud Keychain.
You set up iCloud Keychain in iCloud preferences on your Mac.
To set up iCloud Keychain on your iOS device that has iOS 7.0.3 or later, go to Settings > iCloud on your device. For more information, see your device’s user guide in Safari bookmarks or on the Apple Support website.
Removing credit card information or account names and passwords in Safari deletes them from your OS X keychain and from your iCloud Keychain.
Set up iCloud Keychain on your Mac
In iCloud preferences, turn on Keychain, then follow the onscreen instructions.
Approve a device to use iCloud Keychain
If you set up iCloud Keychain on this Mac, and then you set it up on another device, you receive a notification on this Mac asking if you want to let the other device use your iCloud Keychain.
- Click View in the notification alert, or open iCloud preferences.
- In the dialog that appears in iCloud preferences, enter your Apple ID password, then click Allow.
If you have more than one Apple ID, enter the password for the Apple ID you use with iCloud.
Change how new devices can be approved
After setting up iCloud Keychain on your Mac, you can change whether your iCloud Security Code can be used to approve iCloud Keychain on new devices. You can also change the iCloud Security Code or the phone number used to verify your identity after you use the iCloud Security Code.
