What is the security code maintained by each certified operator?

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

Answer: (A)

In authentication, the credential kept by each certified operator to prove who they are is a password. A password is a secret string that the user creates and guards, used to log into systems and verify identity. It fits the phrase “security code maintained by each certified operator” because it denotes a personal, confidential login credential. A PIN is typically a short numeric code used for devices or payment cards, not the general login credential for system access. A secret is too vague to be a formal credential, and while a passphrase is a longer form of password, the standard term described here is the traditional password.
