If your going to use a chess opening as a password such as 1d4e6Nf3f5 be sure to put one or two
random figures in to make it more secure e.g. 1d4Ae6Nf3Nf5 now all you have to remember is
the two random letters and where you placed them. Here is is A4N7. Now you can keep a
cryptic note of your password word e.g. Holland12A4N7, where Holland reminds you it's the dutch
defence, 12 reminds you of the total length of the password followed by the placement of the
random letters - and you could shift these by a factor as well to further confuse things if more
security is required.
