In a previous tutorial, you learned how you can create a self-signed digital certificate outside PowerPoint, and then mark this as a trusted certificate. This way you can create multiple trusted or non-trusted certificates, and use them within PowerPoint or even other Microsoft Office applications. Although these certificates can be used in PowerPoint, you cannot remove these certificates from within PowerPoint.
To learn more, choose your version of PowerPoint. If we do not have a tutorial for your version of PowerPoint, explore the version closest to the one you use.
