I was recently confronted with a new password policy: my password needed to be a combination of 8 to 12 characters with only numbers and letters. And the numbers were not allowed to be at the beginning or end. My solution was a combination of a standard word with my zip code. But I am not convinced that it is a good password. I will not be able to remember it easily, as it differs from all my other password.
The more you work with computers, the more passwords you generate. I have to remember so many passwords that I use a program to store most of them. It is not the best option but I can only remember so much.
