One-time passwords can be used for only one authentication process in order to gain
access to a system. By using one-time passwords, the probability of an attack relying on the interception and
replay of network traffic is lessened because a previously valid password will
not be accepted on a second or following round. One-time passwords are
typically used in security-Âcritical
environments in which clear-text passwords continue to be used.
