5. (Optional) If you want your personal information stripped from the file, such
as your name removed from the Author field of the Properties box, select the
Remove Automatically Created Personal Information from This File on Save
check box.
6. (Optional) If desired, adjust the macro security level for PowerPoint (all files,
not just this one) by clicking the Macro Security button and making changes to
the settings in the Trust Center; then click OK to return to the General Options
dialog box.
7. Click OK. If you specifi ed a password in step 3, a confi rmation box appears for it.
8. If the confirmation box appears, retype the same password and click OK. If you
specifi ed a password in step 4, a confi rmation box appears for it.
9. If the confirmation box appears, retype the same password and click OK.
10. Continue saving as you normally would.
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.
