Slide Protection allows you to protect selected slides or your whole presentation against unauthorized or unintentional editing. You can access slide protection by right clicking a slide and selecting Slide Protection to the bottom of the context menu.
You have the option to either lock selected slides or the whole presentation. In addition, you can choose to set a password, or lock the slides without one. In addition, you have the option to protect charts from being altered by another party. As soon as you toggle the corresponding option, the chart will be converted into an image.
Once you have protected a chart from later alterations, this setting cannot be reverted. Therefore, it is advisable to save the presentation or slide to your user library beforehand.
You have the same options for Slide Protection via the Send button.
