Yubico makes many different styles of physical two factor authentication devices. These help protect your online accounts by requiring not only a password but also access to the physical device in order to log into a web service.
From now until 30 November, you can get up to 50% off select Yubikeys. They are also offering deals on bulk purchases. I recommend you purchase at least two devices to keep one as your primary and store the other as a backup in case something happens to your primary device.
