PINsafe User Guide

The Security String
Each user is sent a security string. Using the PIN as a positional indicator, a code for authentication is found.

Example 1: If my PIN is 1234 and my Security String is 7 4 6 9 8 3 2 1 6 0 My login code is 7469
Example 2: (we can also use letters) If my PIN is 9371 and my Security String is H R Q B F S Z A M T My login code is MQZH
