Managing Multiple Sessions

Only a single active brokerage session can exist for any username accross all IBKR services. If you are logged in to either Client Portal, TWS, or IBKR Mobile, make sure to log out and try reauthenticating your session Client Portal API again.

Clients wishing to use multiple IBKR products at the same time (TWS, IBKR Mobile or Client Portal) can do so by creating a new username that can then be used to log into other services while using the Client Portal API. To create a second username please see the following IBKR Knowledege Base article.

Note: In accordance with market data vendor requirements, market data services are user-specific and any username subscribed will be assessed a separate market data subscription fee.
