Internet Security has gotten stupid, I usually can remember 4 12didgit passwords with out writing them down, only companies like yahoo are forcing me to change my password every two months, and I can't use the same one I have used before, this has gotten to the point where I just can't keep all the passwords straight.
I have the generic password for things I don't care about 8 digits been the same since 1997.
I have 3 variations of that one at 12 digits long, which I usually use for Email, Video game servers, and my Credit cards.
I have one just for my bank to express my love for banks.
But Yahoo and Google have had 20+ passwords each in the last 2 years. It has gotten that when they ask me for a password I reset it. Because hell if I know what it is.
