Which term refers to a sequence of words used to gain access to a system?

• A. Password
• B. Passphrase
• C. PIN
• D. Token

Answer: (B)

A passphrase is used in authentication as a longer sequence of words that you know. Because it combines multiple words, it creates a much larger set of possible values than a typical password, making it harder to guess or brute-force while often remaining memorable. This is why a sequence of words used to gain access is called a passphrase. In contrast, a password is usually a shorter string of characters, a PIN is a numeric code, and a token is a device or code that you possess to authenticate.
