Quite true; and that is why I emphasized writing down the password. It is all too easy to password protect the VBAProject, continue to work for a while and then close the file without consciously thinking about the password. Several days later you resume work on that file and unless you are consistent in password choices or have an unusually good memory, you may spend some non-productive time trying to remember what the password is.
