I feel prepared for this thread. I have a list with every username and password I use for every site. Not just blatantly scribbled across a page, but with a simple code. It uses various Greek letters and Kanji symbols (among other things) in place of certain letters and numbers. ζ = A, 色 = a, ¤ = B, ﷼ = b, and so forth.
I have exactly fourteen different passwords for 33 different sites/accounts (online games, filesharing accounts, etc.), only 8 of which I actually go to.
For this site, my password consists of the last four digits of my social security number in reverse, followed by the 1st, 3rd, 5th, and 7th digits of my cell number, followed by EoFF and then the word GATE. I try to use an anagram or abbreviation of the each site for its password, and usually incorporate the word GATE into it in some way. I think I'm going to change my password for this site to something more simple, though. Like "cheese" or "BananaHammock" or something.
