Maybe, but it's quite likely to be found and seized when the computer is
seized, and the time to destroy your password is after the computer is
seized but before you are served with a s49 notice.  I would think a
discreet piece of paper (e.g. a cigarette paper) might much more easily
be missed on a search - perhaps slipped in the binding of a book, etc.
