Security Key

Third-party security keys can be used for two-factor authentication. Most of these devices are plugged into a USB port on a computer or laptop and are not intended for use with smartphones. (Note that some high-end versions of these devices do not need a USB connection.) Standard USB security keys cost $25 and up and can be purchased through Amazon.
