Secure your devices
There are a few additional ways to further secure your smart devices. A number of companies now offer a verification system to control access to devices, called two-factor authentication. When you attempt to log into an app, a one-time-use code is sent to another of your devices, which then needs to be entered in the original app. It’s not perfect, but makes it virtually impossible for someone unwanted to access your accounts.
Also, many manufacturers allow you to opt into automatic hardware and software updates, something that will ensure the latest fixes get installed to repair new security vulnerabilities. Make sure you check the settings section of your devices’ apps and your smartphone’s app marketplace for updates to devices that don’t automatically do this.
Ms. Payton said she also reboots smart home devices once a week as an added security measure. “That reboot will actually make it grab any new security and privacy settings and downloads when it reconnects to the internet,” she explained. However, this is impractical for some devices, especially ones that are hard-wired into your home like in-wall dimmers and smart thermostats.
Reset before you resell
Just because you’re ready to ditch a device doesn’t mean it’s ready to forget you. After all, your Wi-Fi password and other personal info is often stored on that camera, smart plug or smart bulb. Before selling or recycling any device, be sure to do a factory reset first. Some devices require a button-press on the actual device, while others allow you to do it from the app. Either way, make sure that your info is no longer available through the app.
If a device is broken and you’re unable to wipe it clean, make sure it’s really broken and smash its components to pieces. According to the United States Computer Emergency Readiness Team, “Physical destruction of a device is the ultimate way to prevent others from retrieving your information.”
I like to think about all those times a device stopped working or disconnected from the network, and the idea of whacking it with a hammer. Just make sure you don’t hurt yourself in the process.
Whose responsibility is security?
There is mounting pressure on manufacturers to adopt better security practices. “The industry should be using strong encryption wherever possible, verifying firmware updates and inviting security audits,” said Bennett Cyphers, a staff technologist at the Electronic Frontier Foundation.
