authentication token(redirected from code token)
authentication tokenA security device given to authorized users who keep them in their possession. To log in to the network, the security "card" or "token" may be read directly like a credit card, or it may display a changing number code that is typed in as the password or in addition to a primary password. USB-based tokens plug directly into the computer.
The code can also be implemented entirely in software, and these "soft tokens" can be generated in a PC or smartphone. See SecurID card, challenge/response, authentication and security protocol.
