If you don’t want others unwanted to open and modify your PowerPoint 2016 presentation at will, you can lock the presentation. Generally, there are two options to lock a PowerPoint 2016 presentation.

Option 1: Lock PowerPoint 2016 presentation to prevent opening

If you want to prevent a presentation from being opened, you can lock it with a password to open. Then anyone requires a password to open the presentation and only those who know the right password can successfully open the presentation. To lock a PowerPoint 2016 presentation to prevent opening, follow the steps below.

Step 1: Open your presentation.

Step 2: Click File. Then select Info tab and click Protect Presentation -> Encrypt with Password.

Click Encrypt with Password

Step 3: Enter a password and click OK. Reenter the password and click OK to confirm.

Type password to open

Step 4: Press Ctrl + S to save this presentation. Then the contents in the presentation are locked by password to open.

Caution: Keep in mind the password. If you lose or forget the password to open, Microsoft won’t provide you any method to recover it and the only option to unlock the presentation is by using a third-party PowerPoint Password Recovery tool.

If you want to prevent your presentation from being edited or modified, you can lock the presentation to make it read-only by the following two ways.

Step 1: Click File -> Save As. Select one location you will save this *.pptx file.

Step 2: In the Save As dialog, click the Tools button at the bottom and then select General Options.

Step 4: When you return back to the Save As dialog, click Save to save this presentation. Then the password to modify will lock this PowerPoint 2016 presentation and prevent it from being edited or modified.

Tips: If you forget or lose the password to modify, Microsoft won’t provide you any access to recover the password. You will have to use a third-party tool to unlock the presentation.
