Which control provides temporary password valid for a single session?

• A. One-Time Password (OTP)
• B. Audit controls
• C. Biometric Authentication
• D. Principle of Least Privilege

Answer: (A)

An One-Time Password (OTP) is a password that is valid for a single session or transaction. It’s typically generated by a hardware token or authentication app and is either time-based or event-based, so it changes frequently and can’t be reused. This single-use, ephemeral nature makes OTPs effective at preventing replay attacks and strengthening authentication when used as a dynamic second factor. Audit controls focus on logging and monitoring rather than issuing credentials. Biometric authentication uses a person’s physical traits for authentication, not a temporary password. The principle of least privilege governs who has access and what they can do, not how temporary credentials are issued.
