Very Good Service from Interactive Brokers

We phoned Interactive Brokers about the login problem. They have a system issue. They set up the account so it can accept a temporary security code which they gave to us. We'll use this until they resolve the issue. The questions they asked to confirm our identity apart from a couple of the typical secret questions were what the net asset value in the account was, what position was in the account (short NASDAQ 100 futures), and what bank we use to transfer money to the account. If we had stolen a password we would have know two of those at least, because you can login into the account on a read-only basis with the password.

I managed to use the temporary security code to set up the mobile app which can produce codes even if it can't receive texts.
