The 'token' in this case (a standard usb thumbdrive) is merely a
portable container for my ssh certificates and a copy of putty (when
I'm on a windows box). You don't need it if you never move around.
What matters is the use of the certificate.

Token may have been the incorrect word as RSA's keyfobs are sometime
called tokens.
