Back when car companies from Mercedes to Ford first implemented key-free unlocking of automobiles, we were quite excited with the convenience upgrade. Now Ford has decided to take the feature one step further and apply their key-free technology to unlocking online accounts we frequent - Facebook, Pinterest and the like. Ford worked with Ogilvy Paris to create this key-free browser extension. It works on Macs with Google Chrome paired with mobile devices with Bluetooth capability. To enable the service, you install the Ford key-free software application onto Google Chrome. Once the software is installed, it can detect all the Bluetooth devices that are within connecting proximity. Select the device you want to use and enter all the login details for sites that you frequent such as Twitter or Gmail. Your mobile or portable Bluetooth device is then synced up as the activator so that whenever you approach your computer with it, you are automatically logged into those chosen accounts. Once you walk out of the room with your mobile or Bluetooth device, those accounts become inaccessible. We're reading that the team behind the app is still working out kinks in the software to try and smooth out the some of the security flaws, such as the ability to login and out if a user doesn't have their Bluetooth device with them. However, we like the type of thinking that went into developing this and enjoy how one concept for cars evolved into a new tool for our online accounts. The app is currently only available in France, so hopefully by the time it rolls out in the U.S. we'll experience the new and improved version.
