PowerPoint is a great application to use for putting together wonderfully creative presentations. Imagine this though - you have just spent hours upon hours putting together the PowerPoint presentation of a lifetime only to find out that another user has come along and made some undesirable changes to it.

You can prevent this from happening by password protecting your presentations. If you use passwords, you have two different options. You can require a password to open the presentation or you can require a password to make any changes to the presentation.

To configure a password, open your PowerPoint presentation and click Options from the Tools menu. Click the Security tab. You will see there are two options available. There is: Password to open and Password to modify. To use either one, simply type a password into the field.
