Protect presentation with password

I must password-protect the strategic plan presentation before sending it to external advisors. Add a strong password to prevent editing, ensure reviewers can view but not copy or print, and deliver the protected file with the password in a separate secure channel to Priya by Monday noon.

Before I lock the deck with a password, surface the trade-offs: show me whether password protection will block viewing on tablets, whether it prevents screenshots, and how it affects our ability to extract speaker notes. Flag any setting that will prevent the board from using the deck during the live session.

I applied a password to the presentation and the CFO reports she cannot open it on her tablet and the meeting is in an hour. I’m panicked about losing access. What likely caused the compatibility issue and what immediate steps will get her a viewable copy without exposing the file to everyone?

We repeatedly lock decks before reviews and then someone can’t open or annotate them, delaying meetings. Which routine should I change — standardize the protection method, share a non-editable PDF version, or require device compatibility checks — to stop last-minute breakages and keep security intact?
