Similar to a password, a passphrase or security key is a secret phrase that helps protect accounts, files, folders, and other confidential information. Passphrases may contain spaces, are several words and 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 a good example of a passphrase.
