This document introduces how to use built-in OTP generator on Smart VPN client and establish a VPN connection to a Vigor Router (VPN server) with Mobile One-Time password (mOTP). While using mOTP, only the client who knows the PIN code, and has the token device with the right secret and time-synchronized with the VPN server, will be able to calculate the correct password for VPN authentication.
