If you want to prevent people from modifying your documents and you use Powerpoint a lot, then you may be interested in this article. Your PowerPoint presentation and all the slides in it are your original, creative work of art. If you work in an office with multiple other office workers, the chances are that somebody might want to steal the content of your presentation and make it appear as his own. Fortunately, you can protect your work from being taken over by somebody. You can protect your PowerPoint presentation with a password. It is easy to do.
First open your PowerPoint presentation and go to File in the upper menu bar. Next, Select Save As. A drop down menu will appear. Choose Security Options here. Now it is time to enter your password. Enter first “Password to open” and after that “Password to modify”. After you are done with that press OK. Now you will have a chance to confirm your password. Remember that your password must contain no more than 15 signs. Simply press OK and save the changes.
This is especially a good idea if your presentation is a surprise or if there is some confidential data there.
