“You don’t want to leave a loose end that could be exposed by a security breach sometime in the future,” Jackson says.Īll sorts of apps can request permission to access the camera, microphone, and other features, such as location information, on your phone or computer. If you want to be extra safe, do what the security pros do and uninstall the app afterward.

In some cases, you may need to download a service you don’t normally use for a specific call or meeting. Any extra effort will leave you better protected.” Just take the steps that make sense for your situation. You also might not have the option to remove apps that come preinstalled on your device, like the Apple FaceTime feature. “For some people, there will be chat apps you can’t avoid because they have features that aren’t available in the browser version of the service,” Feng says. And the experts we spoke with said that major web browsers such as Chrome, Firefox, and Safari are safe and reliable. Using your browser instead of downloading an app is an easy way to stay a little safer.Ī web browser isn’t inherently more secure, but the fewer apps on your machine with access to your camera and microphone, the fewer opportunities hackers will have to break in and spy on you. Most apps like Google Hangout, Zoom, and Skype give you the option to make and receive calls by logging in to their site on your web browser without downloading any special software. “In digital security, we call this your ‘attack surface.’ Reducing that surface is always a good idea.”

“Every time you install a new app on your device, you’re adding another back door into your system, with more potential software vulnerabilities that hackers can try to exploit,” says Cody Feng, project leader for security and privacy testing at Consumer Reports. The only way to be 100 percent safe is to unplug webcams when you’re not using them. Some have indicators for the camera but nothing for built-in microphones. It’s a different story if you’re using an external webcam. It’s far more likely that you’ll fall victim to human error, like forgetting to turn off your camera or using the wrong settings, he says. “Some advanced actors can do more than the average consumer can protect against, but the dangers are not as significant unless you’re a highly valued target,” Jackson says. In theory, a very sophisticated hacker could disable some of these indicators, but that kind of attack isn’t something most consumers need to worry about. But security pros say it’s smart to completely close any video app when you’re done using it.

Windows computers show camera and microphone icons in the task bar, and some manufactures include built-in lights on their Windows laptops as well. On newer MacBooks, you’ll see a green light next to the camera when it’s on, and a microphone icon in the status bar at the top. (Use an app a regular phone call won’t trigger these indicators.)Ĭomputers have similar features.
To test if your phone has this feature, try making a video or a voice call.

On many Android phones, and any phone running the Android 12 operating system, you’ll see a camera or microphone icon pop-up in the top right when an app starts using one of those sensors, which then turns into a green dot. On iPhones running the iOS 14 operating system or higher, you’ll see an orange dot at the top of your screen when an app is using the microphone and a green dot for the camera.
“Now, if an attacker is trying to trick you, you’ll at least know that your camera is on.” “Manufactures have started giving visual clues to users, which make it harder for applications to observe you without your knowledge,” Jackson says. Understanding these signals and keeping an eye out for them is an easy way to protect yourself. Thanks to updates on computers and cell phones, there are easy indicators that let you know when an app has access to the cameras and microphones on your device.
