The intention is that those codes are ready somewhere so that my colleague would not use the same code.
Answer
Dear Carine,
Your question is not so clear. What does preparing the codes have to do with creating them and whether or not using the same code? I would say the best way to make a code is to randomly select a number from 1,2,3,4 six times. You can do this by drawing lots, or you take the first six digits of any number modulo 4. For example, the first 6 digits after the decimal point of the square root of 2 are 414213, just appropriate for your code. In general, you should avoid either not using a number or using a number excessively because this will eventually be noticeable on the keyboard.
However, I don’t think I understood your question, so if you could give some clarification, that would be great.
