A one-time password differs from a typical ID or password in that it is a 6-digit code produced and displayed on the security token's screen each time the token's button is pressed. One-time passwords are very effective against spyware such as key loggers in that they are only valid for a set period of time and become invalid after each use.
A security token is a device that produces a constantly changing, one-time password that can be displayed on-screen with the push of a button. Because the device is separate from any hardware dealing in user authentication,
it provides vastly improved security to the user. A Square Enix security token can be purchased for $9.99.
