When originally setting up file sharing between to MBPs - one user needed a password to file share, while the other did not. I just wanted to speed things up while I was transferring necessary files to the new book. When I was done transferring I decided to assign a connection password for that second user - but I couldn't find how to add it. So I deleted the name from the list & re-created the user was prompted for a password and created one However, the user can still connect to my book without a password??
