Its graphical user interface displays multiple types of keychains (usually including at least two, "Login" and "System" keychains), and also includes a Keychain First Aid tool that can fix keychain problems. There are several possible causes of keychain errors, and sometimes the solution is to delete the old keychain and create a new one, which also deletes all passwords stored in the old keychain.
