implemented as extensions to existing simple-password authentication.
Network Adapter: A network adapter interfaces a computer to a network.
Open Systems Interconnection Model (OSI): The OSI model defines internetworking in terms of
a vertical stack of seven layers.
Server-generated one-time passwords (OTPs): Server-generated one-time passwords (OTPs)
