2. User Accounts: Lesson Eight

Question 1

Which types of items can you store in a keychain?

Answer 1

You use Keychains to store secrets such as resource passwords, digital certificates, and encryption keys.
The keychain system can also securely store Safari AutoFill information, Internet Account settings, and secure text notes.

Question 2

How does the keychain system help protect your information?

Answer 2

The keychain system manages encrypted files that are used to securely save your items.
By default, all users have login and Local Items keychains that use the same password as their account.
Not even other administrative users can access your keychain secrets without knowing the keychain’s password.

Question 3

Where are the keychain files stored?

Answer 3

Each user starts with a login keychain saved at “~/Library/Keychains/login.keychain” and a Local Items (or iCloud keychain) saved in the “~/Library/Keychains/” folder.
Administrative users can manage systemwide authentication assets with the “/Library/Keychains/System.keychain.”
Apple maintains several items in “/System/Library/Keychains/” for OS X system use.

Question 4

What app should you use to manage keychain settings?

Answer 4

You can manage Keychains from the /Applications/Utilities/Keychain Access app.

Question 5

When and why would you set up an iCloud Security Code?

Answer 5

You can set up an iCloud Security Code the first time you enable the iCloud Keychain service for a specific Apple ID.
You can use the iCloud Security Code to set up other devices for the iCloud Keychain service and you can use it to regain access to the iCloud keychain if you lose all your Apple devices.

Question 6

What’s required to set up iCloud Keychain on multiple Apple devices?

Answer 6

You must authorize additional Apple devices to use iCloud Keychain by:
• Using an Apple ID, password, and iCloud Security Code
• Using an Apple ID and password and authorizing access from another Apple device that is configured for iCloud Keychain
