Keychain Keychain Access is a Utility built into Mac OS X that stores your passwords, certificates and other sensitive information securely. However, you may not want to use Keychain Access if someone else has the password to your user account. You cannot completely delete or disable Keychain Access,

but you can delete individual keychains and keys. By deleting every keychain or key, you can prevent anyone from accessing your sensitive information should they ever log in to your user account.
