Add as a preferred source on Google

If you regularly create and give PowerPoint presentations at school or work, you may have at one point wished there was a way to secure your documents with a password easily. After all, you may have sensitive and/or confidential information on those documents that you would prefer to have locked down.

Thankfully, it’s easy to secure a PowerPoint document with a password. In this guide, we’ll show you how to do just that using Microsoft PowerPoint.

We also have steps for setting a password with other presentation software like OpenOffice Impress, a free PowerPoint-like piece of software that’s compatible with Microsoft’s PowerPoint (.ppt) documents.

How to set a password in Microsoft PowerPoint

Password protecting a PowerPoint presentation is straightforward. However, it is only possible in the desktop version of Microsoft PowerPoint. You can enter a password to open a presentation in the Microsoft 365 web version, but you cannot set a password.

In Microsoft PowerPoint on your desktop:

Step 1: Open the presentation you want to protect.

Step 2: Select File, then Info, then Protect Presentation.

Step 3: Select Encrypt with Password, then enter a password. Select OK to confirm.

Note that you have some options for control over the document using passwords. For example, you can set one password for editing the document and another for simply reading it. This lets you determine who can access the presentation to an extent. It is also possible to restrict access to specified individuals. These options can be found in the Protect Presentation submenu.

Finally, you can also set a digital signature to the presentation. This will register attempts to view the document.

How to password protect a PowerPoint document in OpenOffice Impress

First, launch OpenOffice Impress and open the document that you want to put a password on.

Keeping your work secure is important. Make sure you’re employing secure passwords on allof your senstive data, and learn how to password protect a PDF document.

The Mac Pro nearly received an M3 Extreme chip twice as powerful as M3 Ultra
High production costs likely killed Apple’s M3 Extreme plans
Apple's Mac Pro on a table at a press event.

Apple discontinued the Mac Pro earlier this year, ending a 20-year run for a computer that once represented the very best of the company’s desktop lineup. However, Apple reportedly had much bigger plans for the machine before ultimately replacing it with the Mac Studio.

According to Bloomberg’s Mark Gurman, Apple developed an M3 Extreme chip that could have offered twice as many CPU and GPU cores as the M3 Ultra. The processor was intended to sit above the Ultra tier and could have finally given the Mac Pro the performance advantage it badly needed. Apple eventually abandoned the chip due to concerns over production costs and limited demand for such an expensive machine.

Hidden prompts can secretly rewrite an AI’s memory, and researchers say that’s a serious problem
Researchers discover AI attack that rewrites an assistant's long-term memory
Chatbot on a smartphone.

Large language models are getting better at remembering us. Whether it's your preferred writing style, recurring tasks, shopping habits or project deadlines, AI assistants are increasingly storing long-term memories to make future conversations feel more personal and useful. But according to new research, that same feature could become one of AI's biggest security vulnerabilities.

Researchers from New Mexico State University have demonstrated a new attack called GhostWriter, capable of secretly planting false memories inside AI agents. Rather than stealing information outright, the attack manipulates what an AI remembers, potentially causing it to make dangerous decisions long after the original attack has taken place.

This experiment shows how easy it is to poison an open-weight AI model for under $100
This research raises new doubts about trusting open weight AI models.
Computer, Electronics, Laptop

Open-weight AI models have been having a moment lately. Just this month, Moonshot's massive Kimi K3 model landed close behind Claude Fable 5 and GPT 5.6 Sol in several benchmarks, all while remaining fully open-weight and downloadable by anyone.

However, Katie Paxton-Fear, a cybersecurity lecturer at Manchester Metropolitan University and staff security advocate at Semgrep, managed to poison an open-weight model and proved how easily that openness can be turned against you (via The Register).
