What makes you think that?
Such a token uses a cryptoraphically secure algorithm to generate a new number
every minute (or other reasonably small time period). If you don't have the
token then you don't have one half of what is necessary to authenticate
yourself and can't login.
Some tokens just display a number, some require that some sort of pass (either
a password or a code obtained from the server) be entered into the device and
the resulting number be returned to the server. However ssh doesn't support
custom prompts from the server, so the best we could do is to take a code
from the device and append it to a password to send to the server.
