Perhaps one day they will be able to help you create one?

What about the two who created Eternity 2?

You may appreciate by now that this is a highly specialized subject.

That big grid is wasting a lot of space. Now look at this 3x3 grid:

qwe

AsD

Zxc

We'll suppose that we have only nine characters in our alphabet. Suppose we want a 3-
character password. I'll pick the first one in the first row, the last in the second and the first in the
third: qDZ. We are allowed to pick any character more than once. The total number of different
passwords is 9^3 (729). The grid is space efficient. There is no need to print all 729 variants.

It's also very easy to pick the wrong one if you have a huge, huge list of passwords in front of
you. However, most importantly of all, it is extremely inefficient. We have to stop people
programming super supercomputers to try all of the combinations.

We need something clearer and far more efficient than that messy 3x3 grid.

A grid is required, one that can be easily created on a sheet of paper such that if it was lost it
won't matter because the grid can be recreated again on another sheet. So there must be a
pattern that is easy to memorize. And if others peek at that sheet it won't matter because they
have no idea how you are using it to create your passwords.

The grid must be easy to use and it would partially resemble a flower, a rectangular one.

All of the characters in your password will be chosen from the grid. Most of these characters will
be the same each time and will be used in all of your passwords.

With, say, a 20-character password there are 62^20 different combinations (if symbols are
excluded). No one in the world actually needs that number of different passwords over one
lifetime. To simplify the operation for the user a significant trimming would be applied but the
number of different passwords available will still be enough for one person over one lifetime.
What this means is that most of the characters in the passwords will be the same but for a small
selection which need to be different each time.

How would all of the passwords be different? You remember Alooonent mentioned earlier?
Characters from that name are used to obtain characters from the grid which will then form part
of the password. So the next time you need a new password you would obtain a very likely
different combination of characters from the name of the new account's provider. So if you now
