This may be a good reason to change broker. Using a device for trading is quite stupid. Imagine if you are logged out for some reason, how many minutes you have to spend loggin again because of the stupid device.
Besides, like a guy said, this doens't change the fact that a computer can be hacked remotely in a TWS session already logged in.
Another one, suppose that you lost your device, or you get stolen in the street, or the device fall into the floor and its broken.
You wont be able to trade until stupid IB sends you a new device. Amazing.
Clearly, the IB management thinks they know too much about tech and stuff but they don't know shit about real trading.
