I agree, and most systems now have the ability to either reset your password if you don't remember it, or will e-mail you your password if you forget it.

I remember the passwords for systems and Web sites that I use every day, but for non-occasional site passwords, if I can't remember it I just hit the "forgot password?" link and either get a new one that I change later, or have the password e-mailed to me.

Not for the super-secure systems, of course, just different Web sites that I have registrations for...
