The Brazilian brokers use an additional password called digital signature, in order to grant even more safety to the investor. It is mandatory to add the digital signature on the trading panel before you send an order.
Once connected to the Órama trading pane, you must open the Order Panel localized at the right pane, with the pane opened you can find the Digital Signature field. For your convenience, you may check the checkbox Save Digital Signature to fill the password just once.
