Passphrase

Similar to a password, a passphrase is a secret phrase that helps protect accounts, files, folders and any other confidential information. Passphrases contain spaces, are generally several words, and usually also contain numeric characters. Because of the length of most passphrases they are considered safer than passwords. For example: "2 be or not 2 be?" is an example of a passphrase.
