Multiple 2Factor System (M2FS)


This page covers specific points on what the Multiple 2Factor System (M2-FS) is and how it functions. For general questions on the Secure Login System, please refer to KB1131.


Table of contents


What is M2-FS?

M2-FS allows any client to maintain more than one active security device at the same time. No more do you have to pick and choose whether you prefer to use a physical security device or the IBKR Mobile app as either can be used interchangeably.


Back to top 


For any clients with an active security device, any further device activation will result in both devices remaining active.

I currently use the Security Code Card / Digital Security Card+: Clients who currently use a physical security device, simply need to download and activate the IBKR Mobile app. Refer to the directions for Android and iOS for details.

I currently use the IB Key or the IBKR Mobile app: Clients who currently use the IB Key or IBKR Mobile app and qualify for the Digital Security Card+, can proceed to login to Account Management and request that device1 by following the instructions here.


1: The DSC+ is available to accounts with a balance greater than USD 500,000. If your account is below this limit we recommend the activation of the IBKR Mobile authentication, as explained here


Back to top  


Once you have both a Physical device and the IBKR Mobile app enabled, M2-FS is represented by a drop-down menu upon login. You can now choose the device you wish to authenticate with.

  1. Enter your username and password into the trading platform2 or Account Management login screen and click Login. If correct, a drop down option will allow you to Select Second Factor Device:

    TWS Login -> Select Two Factor Device

    Account Management:
    Acct Mgmt Login -> Select Second Factor Device
  2. Once you select a security device, you will now be presented with the corresponding screen for authentication. Refer to the directions for:

    - IB Key via IBKR Mobile (iOS) 
    - IB Key via IBKR Mobile (Android)
    - Security Code Card
    - Digital Security Card+
  3. If authentication succeeds, the Log-in will now automatically proceed.

    TWS Login completes after two factor authentication

    Account Management:
    Ascct Mgmt Login completes after two factor authentication



2: Requires TWS Build 966 and above.

Withdrawal limits

The device used to authenticate your withdrawal, will dictate the withdrawal limit at that time. See details below:

Security Device
used for Withdrawal

Maximum Withdrawal
Per Day

Maximum Withdrawal
in Five Business Days

Security Code Card USD 200,000 USD 600,000
IB Key / IBKR Mobile app USD 200,000 USD 600,000
Digital Security Card3 USD 1,000,000 USD 1,500,000
Digital Security Card+ Unlimited Unlimited
Gold Device3 Unlimited Unlimited
Platinum Device3 Unlimited Unlimited

3: Represents a legacy device that is no longer issued.


For example if you have both the IBKR Mobile app and the Digital Security Card+ enabled and need to withdrawal more than USD 200,000, you can use either device to login to Account Management but will be required to use the Digital Security Card+ to confirm your withdrawal request.


Back to top


M2-FS provides even more flexibility to IB's Secure Login System by allowing you to choose what security device you want to authenticate with. In addition to the convenience of using a device which is trusted and routinely accessible, you can eliminate delays associated with authenticating at times a trade needs to be entered quickly.
