Google Slides is a popular way to create and share presentations. Since you can limit how people view and edit your Google Slides presentation, there is no additional need to password-protect your presentation. However, if you still want to add an extra layer of security, you can password-protect your Google Slides presentation with some workarounds. Let’s check them out!
Method 1: Use MS PowerPoint to Password Protect Google Slides
One of the easiest ways to password-protect your Google Slides presentation is through MS PowerPoint. Here are the steps you need to follow to do so:
1. Open your Google Slides presentation and go to File > Download > Microsoft PowerPoint (.pptx) to download the slide in PowerPoint format.

2. Open the file in PowerPoint. Click on the ‘File’ tab and then select ‘Info.’ Then click on ‘Protect Presentation’ and then select ‘Encrypt with Password.’

3. Enter a password for your presentation and click ‘OK.’ In the next popup, re-enter the same password to proceed.

4. Save and close the PowerPoint presentation.
5. Now upload the PowerPoint presentation to Google Drive by going to Google Drive > New > Upload File.

That’s it. The next time you or anyone else tries to open the presentation, they will be prompted for a password.
Anyone you share the file with will need that same password to open it, so make sure you pass it along through a separate channel rather than tucking it into the share email.

Method 2: Password Protect A Google Slides with a Third-Party Workspace App
No copy of Microsoft Office to hand? You can lock the file using Password Protect for Google Documents instead, a third-party Google Workspace add-on built for exactly this kind of task.
1. Open the Password Protect for Google Documents on Workspace Marketplace.
2. Press “Install” and follow the on-screen guide to complete the download. You might need to grant several permissions to use the program.

3. Once done, go to Google Drive and left-click on the Google Slides that you want to password-protect. Then select “Open with” > “Password Protect for Google Docs”.

4. Once you do so, the file should be uploaded and ready to be password-protected. Enter a password and click “Create Password Protected Document.”

Done! Your Google Slides document is now password-protected and will be saved as a new PDF file in the drive. You will need to enter the password to open it.

Conclusion
If your deck contains sensitive information, locking it behind a password is a sensible step against unwanted access. As you can see, there is more than one route to protecting a Google Slides file. Pick whichever option fits the tools you already have.
