When you (or someone else) open the ﬁ le, a Password prompt appears. The Open password
must be entered to open the presentation ﬁ le. The Modify password will not work. After
that hurdle, if you have set a separate Modify password, a prompt for that appears. Your
choices are to enter the Modify password, to cancel, or to click the Read-Only option to
open the presentation in Read-Only mode.
Here’s a security hole to be aware of: If you add a Modify password and then save it as a .pptx i le, it can be opened
and edited in PowerPoint 2003 or earlier if you installed the compatibility pack that allows opening of .pptx i les,
even if the user does not know the password. However, if you save the i le in PowerPoint 2013 as a PowerPoint
97–2003 i le (.ppt extension), it cannot be edited in earlier versions without the password.
