Encrypt your PowerPoint presentations

Using the encryption feature in PowerPoint is one way to prevent other people from accessing your presentation. The password is assigned by you when you create the presentation. The viewer must enter this password to view your work. If an encrypted presentation is opened with other software hoping to view/steal the content, the viewer will see something similar to the image on the left.

Password protection in PowerPoint 2007

The encryption feature in PowerPoint mentioned above only adds a password to open the presentation. The password feature allows you to add two passwords to your presentation:
• Password to open
• Password to change
Job application password to change let viewers see your presentation, but they can’t make changes unless they also know the optional password you set to make changes.

Mark as last feature in PowerPoint

Once your presentation is done and ready for prime time, you can use the label as a last feature to avoid accidental modification.

Protect PowerPoint slides by saving them as images

Saving completed slides as images ensures that the information remains intact. This method requires a little more work because you need to create your slides first, save them as images, and then paste them back into new slides.
This method should be used if you want the content to remain unchanged. , as is the case for sensitive financial data provided to board members.

Save PowerPoint as PDF file

You can protect your PowerPoint 2007 presentation from any changes by saving or using the appropriate term – publication – as a PDF. This preserves any formatting you apply, regardless of whether the viewer has those fonts, styles, or themes installed. This is a good option when you need to submit your work for review, but the reader can’t make changes.

Security flaws in PowerPoint

The use of the word “security” in relation to PowerPoint is (in my opinion) grossly overrated. Even if you’ve encrypted your presentation with passwords or saved your slides as images, your data could be vulnerable to prying eyes or theft.
