A sequence of words or other text used to control access to data or a computer system or program?

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

Answer: (A)

A passphrase is the best fit because it specifically refers to a sequence of words or text used to authenticate access to data or a system. Its emphasis on words and longer length makes it easier to remember while also increasing security, since longer phrases have more possible combinations than short strings. In practice, you might use a phrase like a sentence or a combination of words, which stays memorable but harder to guess than a brief password. A password is a general term for a secret used for authentication and can be a shorter, non-word string. A PIN is numeric, not typically words, and a token is a device or code used for authentication rather than a text sequence you type.
