As an intresting aside to this, I was buying a car last week with my debit card and as the transaction was high value, the salesman had to phone up the bank to go through extra security and of course, they wanted to speak to me to get extra security details. They asked me a couple of questions one of which was to give a couple of letters of my password. I initially confused this with my on line banking password, but subsequently got the question correct. I said, "sorry about that, it is difficult sometimes to keep track of which password I have used for which purpose" the lady from the bank said - "oh, I use the same one for everything so that I don't forget it"
I did point out that I work in risk management and that it was a risk to keep the same password for everything as once it was cracked, the fraudster would have access to everything.
If the security staff within the bank don't know how to keep their details safe, it makes you wonder what they are doing with ours!
