To password protect a Microsoft Word document or Excel spreadsheet, go to Tools/Options/Security. Enter your password twice, and the next time you open your file, you
will be prompted for your password. This is helpful if you document is sensitive (such as a list of passwords), if you computer is shared by multiple people, or you want to email a private file.
