Final answer:
The event-driven one-time password is TOTP (Time-based One-Time Password). It changes every 30 seconds based on a predetermined algorithm and the current time.
Step-by-step explanation:
The one-time password that is event driven is TOTP (Time-based One-Time Password). TOTP is a type of two-factor authentication where the password changes every 30 seconds based on a predetermined algorithm and the current time. It is commonly used for online banking and other secure systems to provide an additional layer of security.
For example, when logging into a website that uses TOTP, a user needs to enter their username and password as well as the current TOTP code generated by an authentication app on their smartphone. The code is based on a shared secret between the user's device and the server, as well as the current time, ensuring that each code is unique and can only be used once within a short period of time.
