Individual account holders have the ability to add multiple users to their IBKR account. The account holder may wish to add a second user registered under their own name for the purpose of opening two TWS sessions simultaneously (one for normal access and the other for connecting via an API). The account holder may also provide access to up to 5 (non-employee) individuals, such as a family members, pursuant to a Limited Power of Attorney agreement. In addition, each of these individuals may also be provided with a second user access. A second user of an account cannot be provided with funding rights. All other power of attorney users may have funding access if granted by the account holder.
In each case, the additional user will be assigned a unique user name which is required for log in both to Client Portal and the trading platform of choice. Procedures for adding a second user account for access by the existing account holder are outlined below (search
KB1001 for procedures for adding non-employee users).
