Some Office programs provide the ability to assign passwords to protect documents created in that program. For example, in Word and Excel, you can require others to enter a password to open a document, to save changes to a document, or both.

Microsoft PowerPoint® 2000 does not provide password protection capabilities for presentations. You cannot protect the contents of a PowerPoint presentation from modification: when you open a presentation, you can edit the contents. You can assign password protection to VBA (Visual Basic for Applications) projects that are part of your presentation, but not the presentation itself.

For information about assigning password protection to a VBA project in PowerPoint, switch to the Visual Basic Editor, type set project properties in the Office Assistant or on the Answer Wizard tab in the PowerPoint Help window, and then click Search.
