1. Introduction

One-Time Password (OTP) Authentication
One-Time Password (OTP) is another optimum security technology that enables a server to authenticate
you based on a password that is unique every time you try to access a protected network.
Two-Factor Authentication
Two-factor authentication is an optimum security methodology, because it requires something you have
(your ZyWALL OTP Token) and something you know (your secure password or PIN). A two-factor system
is far more secure than using just a password, since many skilled hackers can quite easily access
password-only protected computers and networks. The illustration shows the concept of Two-Factor
authentication.
User PIN and Token code
User PIN is what you know and Token code is what you have.
