For the most part, I simply remember them, since almost all of them follow one of two patterns. But I do have a rather incomplete spreadsheet somewhere for "just in case."

I use my memory, writing things down leaves them open for others

I remember my typical user names, but for the ones that are not, I have them in the bookmarked title for that site. As for passwords, I use a few variations of one, so I have no need to write them down.

Its all up here.

I remember them by memory, although lately I don't even bother memorizing them anymore since Firefox stores my passwords for individual sites, but if my computer crashes I'd have to look for every single password in my memory files, that would suck though. XD
I think that I have around 20 passwords stored in my mind. =3

Writing it down is a security flaw...I memorize them then implement them...

Memory.

This has caused many problems though. There are many times when I end up flicking through all the passwords I can remember ever using if I can't remember which one goes where.

Then you have all that "you have entered the wrong password too many times, the account has been disabled for 45 minuites"

Bleeeh.

I memorize them all. Same goes with my social security and license plate number.

It's not photographic memory (I have a terrible recollection), but imprintization, which I know isn't a real word, but imprinting sounds too Freudian, and I can't find another substitute.

No. I can remember my passwords since I have ones i usually use. I don't remember passwords from a few years ago though. Writing them down might be found.

Lalala~

I used to try to remember, but there are too many systems which have special requirements that won't allow me to use my normal (fairly strong) passwords, so I started writing them all down. IT nightmare, I know, but it can't be helped.

If you've ever thought or said "Nice Guys finish last" and really meant it, then you should probably read this LJ post by DivaLion. It's incredibly insightful whether you're male or female.

My passwords are acronyms. Which I find to be very easy to remember. I have two or three long ones I use constantly for all my passwords. I have more trouble forgetting my username. I do write down my passwords, but it's not the actual password. It'll be the words and whichever numbers I might have added into it, but not the acronym 🙂 I suggest you all do this though~ Real easy to make one up. I can type my passwords out even though it's just a jumble of letters.

So easy to remember that way! Though people tell me it's "confusing."

I just use one password for everything, so I remember it.

No one gives a shit what trite garbage you write here.

I memorize them all. @_@
I make variations of it too.
So if I forget, there's always the handy..."Forgot Your Password?" button.

My passwords are all different from each other, so I remember them but still write them down, just in case..
