How to password protect a PowerPoint presentation

Password protecting a PowerPoint presentation may be required in some situations, for example if you need to prepare a confidential presentation or if you signed a NDA and need to protect your slides from other co-workers.

Although there are some ways to keep safe a PowerPoint presentation (or actually any file) you can password protect a .ppt or .pptx in PowerPoint 2010 using this method.

First, you need to create or edit your PowerPoint presentation.

Under File menu, locate the Info submenu and then choose Permissions.

Here you will find a few other options available that let you to define permissions for the PowerPoint presentation currently opened. The options are:

If you want to setup a password for your presentation, click Encrypt with Password and then you need to enter a secure password to protect your slides.

Remember that if you lose or forget the password, it cannot be recovered (at least with PowerPoint), although someone may be able to decipher it using a brute force attack or something like that. It is advisable to keep a list of your passwords and their corresponding document names in a safe place so you can then remember what password you used for each document. Also make sure that you have the Caps Lock correctly configured, the passwords here are case sensitive.

If you just want to grant permissions then you need to use IRM or Information Right Management. If you don’t have Information Right Management in your computer then PowerPoint will guide you to setup an account and you need to  sign up for the service (it is free) and you need a Windows Live ID.
