The ZyWALL OTP Key Fob, the One-Time Password token, is designed for two factor authentication solution. Every time the user enters a password to login, the password unique and can only be used at one time, that is why it is called One-time Password. One-Time Password (OTP) is an optimum security technology that enables a server to authenticate a user based on a password that is unique each time the user tries to access a protected network.
The starting point of security is to ensure that only authorized people can remotely access the protected network applications and resources. Given enough time for attempts, it's relatively easy for unauthorized intruders to crack a static password. With a one-time password, the risk can be greatly reduced by constantly altering the combination. The ZyWALL OTP authentication token is a chip-based, 6-digit numeric PIN to be used alongside a password for strong two-factor authentication. The ZyWALL OTP solution includes an ASAS server for back-end OTP authentication, and it can be easily integrated with existing ZyWALL security solutions. The
