  That is *NOT* Two-factor authentication.  See
http://en.wikipedia.org/wiki/Multi-factor_authentication for the
details.  Executive summary... Two-factor authentication requires you to
present two authentication factors each time.  I.e. it's A *AND* B.
Your setup is A *OR* B.  The usual implimentations include 2 factors...
1) userID+password
2) a small credit-card-sized unit that generates random-looking
   multi-digit numbers that change every minute.

  In order to logon the user must enter both the userID+password combo
*AND* the current number on the token card.
