How to See Which App Is Using Your Webcam

Start with the permissions list

Every mainstream operating system treats the webcam as a protected resource. Before an app can capture video, it needs your permission. The system keeps a list of apps that have been granted camera access, and that list is the single most useful tool for answering "which app is using my webcam."

The list does two things for you. It shows you which apps are allowed to open the camera at all, and it lets you revoke access from apps you don't use or don't trust. If an app has been removed from the list, it cannot start the camera until you grant permission again. That is the fastest way to stop an unknown app from recording.

You should also remember that the permissions list is about access, not about live activity. It will not always tell you which app is capturing video at this exact second. For that, you need to look at the camera's LED indicator or use hardware controls like a physical shutter (more on this below).

If you want to pair this knowledge with a webcam that gives you more control, see our guide to the best webcams for working from home or the best budget webcams.

On Windows: check the camera privacy page

Windows has a dedicated camera privacy page where you can see which apps are allowed to use the camera. Microsoft explains the mechanics in its support documentation: you start from Start > Settings > Privacy & security > Camera in Windows 11, or Start > Settings > Privacy > Camera in Windows 10.

On that page, the first setting is Camera access. Turn it On so that individual users on the device can choose whether apps have access. Below that is the setting Let apps access your camera. When it is On, Microsoft Store apps can use the camera. Individual apps are listed under "Let apps access your camera," and you can toggle camera access On or Off for each app.

A crucial detail from Microsoft's support page: desktop apps may not appear in the list on the Camera settings page. Desktop apps include apps installed from the internet, a USB drive, or by an IT administrator, and they include browsers like Microsoft Edge and video conferencing apps like Microsoft Teams. For those apps, Windows has a separate master switch called Let desktop apps access your camera. If you want to block all desktop apps from the camera, turn that master switch Off.

This means the Windows permissions list is not always a complete inventory of every app that could use the camera. It is a starting point, but you should also check the desktop apps setting if you see camera activity you can't explain.

For a webcam that works smoothly with Windows privacy settings, look at the best 1080p webcams or the best 4K webcams.

On macOS and Linux: the same idea, a different place

macOS and most Linux desktop environments also maintain a list of apps that have camera access. The general approach is the same as on Windows: find the camera permissions section in your system settings, review which apps are listed, and remove any that you don't recognize or no longer use.

On macOS, look in the Privacy & Security area of System Settings. Camera access is listed there as a separate item. Apps that have requested permission appear in the list, and you can toggle access off for any app. When you first install an app that wants to use the camera, macOS prompts you to allow or deny access, so the permissions list grows over time. Reviewing it periodically keeps things tidy.

Linux is more varied because there is no single desktop environment. GNOME, KDE Plasma, and other desktops generally expose camera permissions through their Settings or Privacy panels. Some distributions also let you manage camera access at the system level. The exact wording differs, but the principle is identical: look at the list of apps with access, remove anything you don't need, and be careful about granting new apps camera permission.

If you want to understand how these permission models interact with the camera hardware, read about the UVC webcam protocol and about multiple apps using the camera at the same time.

What the permissions list cannot tell you

The permissions list tells you which apps are allowed to use the camera. It does not tell you which app is recording right now, and it does not tell you how often each app uses the camera. If you need to know exactly which app has the camera open at a given moment, the list alone will not answer that.

One reason is that desktop apps on Windows can be excluded from the per-app list entirely, as Microsoft notes. Another reason is that the camera hardware itself does not know which software is using it. A webcam that follows the USB Video Class (UVC) standard works with a generic system driver and does not require a proprietary driver from the manufacturer, as described in Microsoft's driver documentation. Because the camera is hardware-agnostic on the software side, the system has to keep track of which app is accessing it, and that tracking happens in the operating system rather than in the camera.

What you can do with the permissions list is remove the apps you don't trust and then verify activity with other signals, like the camera's LED.

Use the LED and a physical shutter as backup

Most webcams have an LED that turns on when the camera is capturing video. This is a hardware signal: if the LED is lit, something is actively using the camera, regardless of what the permissions list says. If the LED is off, you can be confident the camera is not recording.

Some webcams go a step further and include a physical shutter. Razer's Kiyo Pro Ultra, for example, has a built-in shutter that you twist to cover the lens at the end of a session. Similarly, many webcams come with a lens cover or privacy cover that you can attach over the front of the camera. A physical shutter is the strongest guarantee because it blocks the lens entirely, software cannot override it.

When you're shopping for a webcam, look for models with either a built-in shutter or a snap-on privacy cover. See the best privacy cover webcams for models that include this feature, and read our article on privacy shutter types to understand the different designs.

Build a camera setup you can trust

Now that you know how to check which apps have camera access on your operating system, you can apply that knowledge when you buy your next webcam. Look for three things: a model with a clear LED indicator, a physical shutter or privacy cover, and good system compatibility with the OS you use every day.

If you spend most of your time in video calls and want a camera that works well with default settings, a 1080p webcam is a balanced choice. If you're on a tight budget, start with the best budget webcams. If you want the highest detail for streaming or recordings, a 4K webcam gives you more headroom. And if privacy is your top concern, a webcam with a privacy cover removes most of the worry.

Whatever you pick, get into the habit of reviewing your camera permissions once a month. That small habit gives you visibility into every app that could be using your camera, and it takes less than a minute. Combined with a physical shutter, it is the most direct answer to the question "which app is using my webcam?"

What to pick for your use

Questions

Where do I see which apps can access my webcam on Windows?

Open Settings, go to Privacy & security (Windows 11) or Privacy (Windows 10), then select Camera. The page shows the master Camera access switch, the "Let apps access your camera" setting, and the list of Microsoft Store apps with per-app toggles. Desktop apps are controlled separately by the "Let desktop apps access your camera" setting.

My webcam LED is on, but I don't know which app is using it.

Check the camera permissions list on your operating system first. If an app has been granted access recently, it will appear there. If the list doesn't help, close apps one at a time and watch the LED. When the LED goes off, you have found the app. Some webcams also have a physical shutter, which lets you block the lens immediately while you sort out the software.

Does the camera permission list on macOS work the same way as Windows?

Yes, the general idea is the same. macOS keeps a list of apps that have asked for camera access, and you can toggle access off for each app. The exact menu path is in System Settings under Privacy & Security, where camera access is listed as its own item. Apps you deny will not be able to use the camera until you grant permission again.

Is there a way to know which app is using the camera on Linux?

Most Linux desktop environments provide a camera permissions or privacy panel where you can see which apps have been granted access. Additionally, some desktop environments show a camera indicator when the camera is in use. If you need a system-level view, you can check the list of processes that have opened the camera device file, but the permissions list is the friendliest starting point.

Can I stop an app from using my webcam without uninstalling it?

Yes. On Windows, turn off the toggle for that app on the Camera permissions page, or turn off "Let desktop apps access your camera" to block all desktop apps at once. On macOS, toggle off access for the app in the Privacy & Security settings. On Linux, either toggle off the app in the desktop's permissions panel or remove it from the group that has camera access. The app can still be installed, but it won't be able to open the camera.
