Google has launched a USB security accessory dubbed the Security Key, a physical solution for safer two-step verification, according to Digital Spy.

The tool eliminates the need for email or text message verification by allowing the user to authenticate logins by plugging it into their PC's USB port.

The Security Key was launched as a defence against some of the more sophisticated hackers out there, who are able to infiltrate two-step verification systems by setting up copycat sites that request login data from the user.

Google's new accessory uses cryptography to protect the user and is only designed to work with websites it has been pre-programmed for.

The Security Key is programmed to work with Google's Chrome Browser only, which is bad news for Firefox and Internet Explorer users.

Amazon is currently selling three versions of the device, ranging from $5.99 to $50 in price.
