About PowerPoint OpenXML Protection
Standard PowerPoint presentations support the OpenXML modifyVerifier specification in ppt/presentation.xml. When configured, PowerPoint prompts users to open the deck in Read-Only mode unless the authorized modifier password is provided. It also disables accidental layout shifts, master slide corruption, and font deletion when distributing decks to clients or webinar attendees.
