Adding Password Protection to a Presentation You can assign a password and other security options so that only those who know the password can open the presentation, or to protect the integrity of your presentation as it moves from person to person. At times, you will want the information to be used but not changed; at other times, you will want only specific people in your office to be able to view the presentation. Setting a presentation as read-only is useful when you want a presentation, such as a company-wide bulletin, to be distributed and read, but not changed. Password protection takes effect the next time you open the presentation. Add Password Protection to a Presentation -
