To mitigate a risk of password compromise, a company is using a system that is able to issue tokens that change numbers after every 40 seconds. Which mechanism of authentication is this?
TOS
EAP
TOTP
TGT
This is a time-based-one-password-algorithm, named so for obvious reasons. Other options are irrelevant to the characteristics described in the question. The Time-based One-time Password Algorithm (TOTP) is an algorithm that computes a one-time password from a shared secret key and the current time. It has been adopted as Internet Engineering Task Force standard RFC 6238,[1] is the cornerstone of Initiative For Open Authentication (OATH), and is used in a number of two-factor authentication systems.
TOTP is an example of a hash-based message authentication code (HMAC). It combines a secret key with the current timestamp using a cryptographic hash function to generate a one-time password. The timestamp typically increases in 30-second intervals, so passwords generated close together in time from the same secret key will be equal.
