Fully agree on that one... passwords are a very social thing. Many times in
the past I reset the password for people whom I simply trusted. They
claimed their true identity using obvious things like name and username.
When I contact call centres, I am often, if not always, asked for full
address and phone number (and they are lenient when it comes to
correctness)... yeah, like addresses are not obvious... The illusionary
security... making the cutomer feel like there is a line of denfence...

Going back to my previous point, it is hard to prove one's identity over the
telephone and difficult to argue if a senior professor is on the other side
of the line. Also, how does the customer know that it is not, let us say, a
cleaner who answered to phone and is up to no good?

...or logging in using the default, uninitialised machine password, then
changing the desktop picture and leaving objects in the Desktop urging the
users to protect the system. (Script Kiddie Gary McKinnon)

There is a need for development of encryption or authentication over the
phone, maybe with the aid of 2 nodes (machine at the both ends).
