Microsoft PowerPoint is one of the most useful presentation software with features designed to help users create highly effective presentations. PowerPoint is used in various fields and can hold information that is both important and sensitive. As such, locking a PowerPoint presentation can become a necessity. You may need to protect the document from editing to prevent accidental changes that may interfere with the presentation or you may need to password-protect the presentation to keep the information from unauthorized individuals.

Understanding how to lock PowerPoint from editing can therefore be one of the most important skills to have as you will be able to protect the document from exploitation from unauthorized users. In this article, we are going to share with you various ways to lock a PowerPoint presentation.

This method allows you to restrict editing on the PowerPoint document, but it will not prevent someone from opening the document. Here's how to do it;

Step 1: Open the PowerPoint Presentation you would like to protect or create a new presentation.

Step 2: Once you have completed working on the presentation, click on "Info", then select "Protect Presentation" and click on "Mark as Final".

Step 3: You should see a notification that the presentation has been marked as final. Click "OK" to close the notification. Save the changes and when you open the document again, you'll see a message at the top saying it is "Marked as Final".


This is not the most secure way to protect the document since someone can just click on "Edit Anyway" to make it editable again.

2. Set Modify Password

Step 1: Open the PowerPoint presentation you would like to protect and then click on "File > Save As".

Step 2: Select a location to save the file and then click on "Tools > General Options" in the Save As dialogue box.

Step 1: Open the PowerPoint presentation you would like to protect and then click on "File".

Step 2: Click on "Info" and then choose the option of "Protect Presentation".
