Time-Based One-Time Password

Definitions

1. A short authentication code generated from a shared secret and the current time window. It shows up in application security, identity, infrastructure, or incident response work depending on the environment. Teams use the concept to prevent abuse, detect adversary activity earlier, or define stronger control boundaries during engineering, testing, and operations.

   In plain English: Time-Based One-Time Password is the practical security idea behind a control, weakness, or safeguard. It matters because it changes how attackers succeed or defenders reduce risk.

   Example: "During the review, the team focused on Time-Based One-Time Password after telemetry and testing showed it was the fastest way to reduce exposure, tighten controls, and close a realistic attack path before the next production release."
