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.
1. Mark as Final
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
If you want a more secure way to lock PowerPoint from editing, the best way to do it is to set a modify password. This way, anyone without the password will be unable to open the presentation. Follow these simple steps to do it;
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 3: Enter a password in the "Password to modify" box and then click "OK".
Step 4: Go back to the "Save As" dialogue box and then click "Save" to finish. The next time you open the presentation, you will be required to enter your password.
3. Set Opening Password
Instead of setting a modify password that prevents other users from editing the PowerPoint document, you can also set an opening password that can be used to prevent someone from opening the file without a password. Here's how to do that;
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".
Step 3: Select "Encrypt with Password" from the drop-down menu.
Step 4: Enter the password and then click "OK". Reenter the password when prompted and then click "OK" again to confirm it.
Save the document and the next time you try to open the password, you will be required to enter the password to unlock it. Keep in mind that PowerPoint doesn't give you an option to recover the password. So, ensure that you choose a password you can remember and note it down somewhere for future references.
4. Save as PDF or PPSX
Since it is very hard to edit PDF or PPSX files, so you can lock a presentation by save it as a PDF or PPSX file. Here's how to do it;
Step 1: Open the presentation and then click on "File > Save As".
Step 2: Select the location to save the file and in the "Save as Type" dropdown menu, choose either PDF or PPSX.
This is a great way to share the PowerPoint without having to worry that the document will be edited. The original file will however be edited.
