Encrypt with Password Option in PowerPoint 2007 for Windows

Why would anyone want to password-protect their PowerPoint presentations? There are many reasons, and here are some of them:

1. A presentation with confidential content can be prevented from being edited if it is password-protected. Nobody without access to the password can open or edit the presentation file.
2. The password-protected presentation is safer to share, you can provide the password to the person whom you are sharing the presentation with.
3. In addition to providing a password-to-open option, PowerPoint provides a less restrictive password-to-modify option. So your presentation can be opened by anybody, but can't be modified, this makes your content non editable.

Follow these steps to password-protect your presentation in PowerPoint 2007 for Windows:

1. Open the presentation, and click the Office Button and select the Save As option, as shown in Figure 1, below.
2.
