I use algorithm to create a password containing upper and lower case characters, numbers and special characters that is unique for that one place but not random using an algorithm. It is pretty easy to remember even though it contains a simple substitution cipher. It also produces pretty long passwords(The shortest being 13 chars and the longest being 70 chars). Even if it is pretty easy to use and it produces pretty strong passwords I use much stronger algorithm for my root/admin passwords. It is designed to be hard to do but easy enough that you can do it on your head and password is so complex that you can’t remember in in your head, but the components that produce the password are(2 min. 8 char not word chars strings, 3 number sequences and 2-3 special char strings). It produces passwords from 25 chars and up. I desingned it to secure system from both software and users(me).
