The Many Reasons Why We Need 2FA (Two-Factor Authentication) On Smart Home Devices
The lack of two-factor authentication (2FA) on smart home devices is a serious concern indeed. Without the much-needed second layer of account protection, it is easy to be exploited.
While we often discuss IoT device exploits that require a network connection, losing control of a device account doesn’t always require network access.
Without 2FA, it would be easy for someone to get our account credentials and remotely disable the system monitoring and we would be none the wiser until it is too late!
However, if 2FA is implemented, any ill-intentioned hackers would need to go through two levels of authentication before being able to access anything which makes it much harder for them. In many cases, 2FA relies on another device, dongle, USB key, or constantly rotating numeric code. While it might not be a serious concern if all one has in the house is smart lights, but if you have smart cameras or devices that control and manage temperature or water flow, it is critical to be safe and have 2FA.
