Why Lock a PowerPoint Presentation?

Here is why you need to protect your PowerPoint presentation:

  • Protect against any unauthorized changes

  • Keep sensitive data safe

  • Preserve the formatting of the presentation

  • Prevent any mistakes while collaborating with others

  • Stop copying the contents of your presentation

  • Limit access to presentations that contain sensitive data

If you have specific security needs, then there are two levels of protection – read-only and password-based protection.

#1: How to Password Protect a PowerPoint?

One of the best techniques for how to lock PPT from editing is through the use of password protection on the presentation. Password protection will help ensure that no one can access the presentation file without knowing the right password. Microsoft recommends using the “Encrypt with Password” option.

Steps for Password Protection of a PPT File:

  1. Open your PowerPoint file.

  2. Go to File at the top of the screen.

  3. Click Info.

  4. Click Protect Presentation.

  5. Choose Encrypt with Password.

  6. Set up a password.

  7. Click OK.

  8. Retype the password.

  9. Save the file.

Pros

  • Ensures good security of the file

  • Protects sensitive information

  • Easy to implement

Cons

In case you forget the password, you won’t be able to access it through PowerPoint.

#2: How to Password Protect a PowerPoint for Editing Only?

In order to protect your presentation from editing and at the same time allow viewing by other people, use the “Password to Modify” feature.

It is a very effective approach for businesses that share their presentations with clients, staff, or students.

Here are the Steps:

  1. Open your PowerPoint document.

  2. Go to File → Save As.

  3. Specify a location where to save your document.

  4. Click on More options.

  5. Under Save dialog window click on Tools at the bottom.

  6. Click General Options.

  7. Type a password into the Password to Modify field.

  8. Click OK.

  9. Retype the password.

  10. Save your document.

Now other people will be able to view the document, but they will not be able to edit it without a password.

The above method is one of the most effective ways to secure PPT from editing while still allowing viewing.

#3: How to Lock PPT for Read-Only

The read-only mode deters editing and will come in handy if you want to have people view the content but not make any changes.

Way to Lock PPT in Read-Only Mode:

  1. Launch your presentation.

  2. Navigate to File → Info.

  3. Choose Protect Presentation.

  4. Select Always Open Read-Only or Mark as Final.

  5. Save the file.

Upon opening the presentation, PowerPoint will alert the viewers that it’s a final copy that shouldn’t be edited.

Pros

  • Fast and simple process

  • Deters accidental editing

  • No password needed

Cons

  • Viewers can still click “Edit Anyway”

  • Not secure enough for sensitive information

This way to lock PPT from editing is pretty simple.

#4: Restrict Access Permissions

Information Rights Management (IRM) is available in Microsoft PowerPoint that gives you the ability to provide permission to certain users.

Steps

  1. Open your presentation.

  2. Go to File → Info.

  3. Choose Protect Presentation.

  4. Then choose Restrict Access.

  5. Click on Restrict Access.

  6. Select the authorized users.

  7. Set their permission level, including:

    1. Read

Using this feature, only authorized users can make changes to the document, and others will have read-only permission.

Advantages

  • Permissions for users

  • Appropriate for corporations

This approach is especially handy when thinking about protecting PPT from editing and copying.

Generic approach is to Convert PPT to PDF:

  1. Open your presentation.

  3. Select PDF.

  4. Save your file.

It is harder to change PDF files than PPT slides.

You may also use password protection for PDF files.

It is a popular method among companies which want to find out how to protect PPT from editing and copying.

In case your PowerPoint Presentation is saved in Microsoft OneDrive or in SharePoint, then one can create a view only link.

Process:

  1. Upload your presentation in OneDrive.

  2. Select Share.

  3. Choose Anyone with the Link or Specific people.

  4. Turn off the option ‘Allow Editing’.

  5. Copy and distribute the link.

Here’s yet another efficient way to lock ppt from editing.

What If You Forgot the Password?

At times, there arises an instance when the user locks the presentation and then forgets the password.

In these instances, the use of password recovery software will be useful in either recovering or removing the forgotten password from the available PowerPoint files.

In regard to this, you can consider the SysTools PowerPoint Password Recovery Software.
