It’s highly unlikely that someone will hack into your Nest cameras, but it has happened. And if you don’t enable two-factor authentication on your Nest account, it could eventually happen to you.

One family’s Nest camera was recently hacked and used to belt out a fake emergency message about an impending missile strike from North Korea using the Nest Cam’s built-in speaker—a bizarre way of using the hacked camera for sure.

Google says this hack job was merely accomplished by using a compromised password that was also used on another website that was breached. Turning on two-factor authentication would have prevented the Nest camera from getting hacked.

There was also another instance of a Nest Cam (being used as a baby monitor) becoming compromised where the perp started shouting expletives through the camera’s speaker. What’s wrong with these people? It’s just weird.

Long story short, Wi-Fi cams can get hacked into. With that said, if you don’t have two-factor authentication enabled for your Nest account, here’s how to do it.

Go to home.nest.com in a web browser (you can’t do it from the app, unfortunately) and log in to your account.

Tap on your account profile in the top-right corner of the screen.

Select “Settings” from the drop-down list.

Scroll down and tap on the toggle switch under “2-Step Verification.”

Enter in your mobile phone number and tap “Send Code.” This is the phone number that verification codes will be sent to via text (SMS two-factor authentication isn’t great, but it’s absolutely better than nothing).

Enter in the six-digit code that was sent to you and enter it in the boxes. Then tap “Continue.”

Hit “Done” at the bottom to complete the setup.

Now, whenever you need to log in to your Nest account, you’ll be sent a text with a code that you’ll enter in.
