Control App Access to Your Hardware

Learn how to manage which applications access sensitive hardware like cameras and microphones. Reviewing these permissions helps stop background apps from snooping on sensitive hardware.

Each hardware page has a master switch at the top, a list of individual apps, and a separate switch for desktop apps. Check all three. If you turn the master switch off, no app can use that device, even apps you have allowed individually. Do a quick review every few months, since new apps often ask for access when you install them.

Common questions

How do I change my 🪟 Windows 11 password?

Change credentials by navigating to Settings › Accounts › Sign-in options. Follow these steps:

1. Open Settings › Accounts › Sign-in options
2. Expand the Password section. If you do not see it, your account may not have a password set, or the device may be set to allow only Windows Hello sign-in.
3. Click Change.
4. Enter your current password when prompted.
5. Type the new password, then type it again to confirm it.
6. Finish the prompts. The new password applies the next time you sign in or unlock the PC.

If you sign in with a Microsoft account, the change affects that account everywhere you use it, not just this PC. Windows may ask you to verify your identity first, so have your phone or email ready. Choose a long, unique password that you do not use anywhere else.

What is Windows Hello?

Windows Hello replaces traditional passwords with biometric login (using facial recognition or your fingerprint) alongside a secure PIN.

To set it up, go to Settings › Accounts › Sign-in options and pick the method you want. Then click Set up and follow the prompts. You must verify your identity with your current password or PIN first. You always set up a PIN as a fallback in case the camera or fingerprint reader fails.

If an option is greyed out or missing, your PC probably lacks the hardware. Face recognition needs a compatible infrared camera, and fingerprint recognition needs a fingerprint reader. A regular webcam will not do for face sign-in.

How can I see if an app has used my camera?

To see which apps have used your camera, follow these steps:

1. Open Settings › Privacy & security › Camera
2. Check that Camera access is set the way you want. Turn it off to block the camera for every app.
3. Scroll to the list of apps and review each one. Switch off any app that has no reason to use the camera.
4. Look for Recent activity. Under it, you will see which apps accessed the camera recently and when.

Use this list to spot misuse. If an app you do not use, or do not recognize, shows recent access, turn its permission off and consider uninstalling it. The Microphone page in the same menu works the same way.

Why is my computer asking me to sign in with a PIN?

Windows 11 frequently encourages adopting a PIN for faster sign-ins that offer higher security than standard passwords. The code links directly to the user account and remains specific to the physical hardware.

That is why a PIN is safer than a password. If someone learns your PIN, they cannot use it on another computer. To set one up:

1. Open Settings › Accounts › Sign-in options
2. Select PIN (Windows Hello), then click Set up. If you already have one, you will see Change PIN instead.
3. Verify your identity with your account password if asked.
4. Enter the new PIN, then enter it again to confirm. Select Include letters and symbols if you want a stronger PIN than numbers alone.
5. Click OK. From now on, use the PIN on the sign-in screen.

If you forget it, use the I forgot my PIN link on the sign-in screen to reset it.

How do I make sure Microsoft Defender is running?

Microsoft Defender runs automatically in the background. Verify its status by navigating to Settings › Privacy & security › Windows Security Then:

1. Click Open Windows Security if the app does not open directly.
2. Click Virus & threat protection. This page displays operational status and launches manual scans.
3. Check the status. A green check means no action is needed. Any warning will include a button to fix it.
4. Click Quick scan to run a scan now. Use Scan options if you want a full scan instead.

If Defender appears to be off, you may have installed another antivirus program, which normally takes over and turns Defender's real-time protection off. That is expected. If you have no other antivirus installed, make sure Real-time protection is on under Virus & threat protection settings.
