Thanks for playing! The algorithm to take the passwords is:
1.- From a dictionary I pick a random password. All words have 6 letters.
2.- From the same dicitionary I pick 3 random passwords which has at least 3 letters in common with the password.
3.- Same as above but 3 words with 2 letters in common and 3 words with 1 letter in common. Then 2 words with no letters in common to complete 12 words.
So one little trick is that sometimes you "see" some words that looks the same, and one of those is 99% of the times the correct password.
