Communication system and method for managing guest user network connections

A communication method comprising:

• connecting communication made from a terminal apparatus via a first communicator and addressed to any destination, to an authentication unit;
• transmitting, by the authentication unit, an authentication screen for inputting authentication information by a guest user, in response to access from the terminal apparatus, wherein the terminal apparatus is outside a network organization of a host user;
• receiving, by the authentication unit, the authentication information input to the authentication screen;
• displaying, to the host user, the authentication information input to the authentication screen and output by the terminal apparatus that has been connected to the authentication unit at the connecting and to which the authentication screen has been transmitted,
• the authentication information being received by the authentication unit;
• receiving a user input by the host user;
• and
• permitting connection of the terminal apparatus to the network via a second communicator in accordance with the host user input received according to display at the displaying when the host user input indicates that the host user authenticates the terminal apparatus after displaying the authentication information that is input to the authentication screen transmitted by the authentication unit to the terminal apparatus and received by the authentication unit from the terminal apparatus,
• the authentication information being input in the terminal apparatus by the quest user is separate from the host user input at the input unit by the host user,
• the terminal apparatus is permitted to connect to the network via the second communicator after the terminal apparatus is authenticated via the first communicator.

A non-transitory computer-readable medium including programmed instructions that cause a computer of a communication apparatus to execute:

• connecting communication made from a terminal apparatus via a first communicator and addressed to any destination, to an authentication unit;
• transmitting, by the authentication unit, an authentication screen for inputting authentication information by a guest user, in response to access from the terminal apparatus, wherein the terminal apparatus is outside a network organization of a host user;
• receiving, by the authentication unit, the authentication information input to the authentication screen;
• displaying, to the host user, the authentication information input to the authentication screen and output by the terminal apparatus that has been connected to the authentication unit at the connecting and to which the authentication screen has been transmitted, and the authentication information being received by the authentication unit;
• receiving a user input by the host user;
• and
• permitting connection of the terminal apparatus to the network via a second communicator in accordance with the host user input received according to display at the displaying when the host user input indicates that the host user authenticates the terminal apparatus after displaying the authentication information received by the authentication unit that is input to the authentication screen transmitted by the authentication unit to the terminal apparatus and received by the authentication unit from the terminal apparatus,
• the authentication information being input in the terminal apparatus by the quest user is separate from the host user input at the input unit by the host user input,
• the terminal apparatus is permitted to connect to the network via the second communicator after the terminal apparatus is authenticated via the first communicator.
