passphrase - Computer Definition
Text string consisting of several words and numbers that a user enters to access a computer, network, or an applicaiton. Some systems allow users to use entire passphrases rather than a short string for passwords. Though passphrases are deemed to be more secure because they are harder to crack, they are generally used only when extreme security is demanded.
