One solution would be to use password safes that store all your passwords securely and can only be opened with a master password. Another method would be to use Password Grids, let me explain the concept. You use an 8×8, 10×10 or bigger grid and create one easy to remember pattern on it.

You could write big letters or numbers on it for instance or draw simple objects, something that is hard to guess but easy to remember. You write it down on the grid using numbers to remember the sequence.

The second step would be to use a second password grid with random chars to substitute the real password.

You create one random grid and a pattern for every login that you have. Once done you only carry the random password grid with you and leave the other cards at home. The ultimate solution would be to remember the objects without having to store the cards at home. You could deposit them at your local branch instead for instance.

Is this system the most secure ever ? Not really. If someone gets hold of your random grid it would be relatively easy to apply the most used forms (letters, numbers, chars) on it. A supercomputer could do this in a short time. They would also know exactly which chars could be used to generate the passwords.

Another problem would be that you still have to remember all the patterns that you have created which would pose almost the same problems than remembering the passwords directly.

This system does not work where someone else is handing out a password to you which can’t be changed.

So, it is nice if you do not fear that someone with enough energy and power is spying on you and wants your passwords badly. If you only fear identity theft this could be a solution.
