At home, I will make a terible admission, my user IDs and passwords are scotch taped to the boxes.........I have a wife .............and they are very complex passes.

IMO in some situations(such as homes) it is not -horrible- to write down the passwords for something. as long as the area they are in has good physical security, and it is ok for everyone that has access to that area to have the passwords, then its not such a big deal. For home computers where everyone is using it, and they are going to be sharing an account anyway, passowrds are reallly only there to stop remote access.
