Don't ever forget a password again! It ingenious, I don't know how they come up with these ideas.
But seriously, who would want to store all of their passwords in a little book that anyone could take and then have access to everything you own online? So, would/do you guys actually use something where all your passwords are in one location? Or do you use some sort of password vault software to store your passwords? Maybe you just have the greatest memory ever and store them in your head. Let me know what you guys are using, unless you don't want the whole world to know they are on that sticky note stuck to the bottom side of your drawer.
