Password Mayhem

These days you need a password for just about everything. And for security each password should be different and hard to guess. This means that keeping track of website username password combinations is extremely difficult. One possibility is to use a substitution cipher that makes a simple easy to remember password, like “bank” and turn it into one that looks “hardened”.

Two minor drawbacks: 1) Never lose the original cipher. 2) If the “bad guy” gets a set of several of your passwords, a substitution cipher is easily cracked. That being said, it would be a rare chance for someone to acquire several of your passwords to break the code.
