Protect presentation

PowerPoint 2016 2013 2010 2007
Suppose your presentation contains sensitive or confidential data, or you might want only certain people to be able to open and modify a presentation. In that case, you can encrypt the file and protect it with a password. Generally, to ensure that no one can change the presentation, it is better to save the presentation as images or as a PDF file.

You can protect the file by assigning a password to a presentation. PowerPoint offers two different types of passwords for a file:

  • the Open password - to prevent unauthorized people from viewing the file at all
  • the Modify password - to prevent people from making changes to the file.

To manage file passwords and other security settings, do any of the following:

   A.1.   On the File tab, select the Save As pane, then do one of the following:

  • Click the More options... link:

  • Click Browse to open the Save As dialog box.

   A.2.   In the Save As dialog box, click the Tools button:

Note: If you want to protect a copy of the presentation instead of the original, enter a new name for the copy in the File name field.

   A.3.   From the Tools dropdown list, choose General Options...:

  • If you want an Open password, enter it in the Password to open field.
  • If you want a Modify password, enter it in the Password to modify field.

    Note: You can use both an Open and a Modify password or only one of them.

  • Select the Remove automatically created personal information from this file on save checkbox if you want to delete the personal information from the file, e.g., your name will be removed from the Author field of the Properties area (see more about hidden information in Microsoft files).
  • Optionnaly adjust the macro security level for PowerPoint (all files, not just this one) by clicking the Macro Security... button and making changes to the settings in the Trust Center:
