does not really apply since you need two factors to get in.  In the
case of 2fa the links are in parallel not series.

Yeah, the chain was a bad metaphor.  My point is with two factors you can
still end up with only a single factor because one is so weak or badly
implemented.


In any case having 2fa does not mean that one should ignore password
altogether.  At the moment I am leaning towards retaining passwords for
low value/risk stuff and augmenting them with some for of One Time
Password device for things that really matter.

Great!  A risk management approach.


Ideally I would like to see our ID and Building Access (proximity)
cards combined (the university is actively looking at this now) along
with a smart card that comes in two flavours one which just has storage
for certificates and one that has full blown crypto built in.

Why not some of the smart phone stuff like the VeriSign's VIP for Mobile
<http://www.verisign.com/authentication/two-factor-authentication/vip-access
-for-mobile>?  No reader to buy, no card to purchase.
