How to reactivate or transfer the IBKR Mobile authentication?


This article details the steps needed to reactivate the IB Key authentication via IBKR Mobile.

This state of the application or its installation might be due, but not limited to, reinstallation of the app or the purchase of a new phone.


You can perform the reactivation without the involvement of IBKR Client Services in the following cases:


Case A) Reactivation on the same smartphone

  • You uninstalled and reinstalled the IBKR Mobile app on the same smartphone

Please click on one of the links below according to your phone operating system.

  • Android: IBKR Mobile PIN + Access to the mobile phone number originally used for the app activation
  • Apple iOS: Smartphone PIN / Fingerprint / FaceID + Access to the mobile phone number originally used for the app activation


Case B) Reactivation on a different smartphone

  • You are replacing your smartphone with a new one
  • You have lost your smartphone and you are now in possession of a new one
  • You activated the IBKR Mobile authentication on your primary smartphone but you now want to transfer
    the activation (either temporarily or permanently) to the secondary one.

Please click on one of the links below according to your phone operating system.

  • Android: Access to the mobile phone number originally used for the app activation
  • Apple iOS: Smartphone PIN / Fingerprint / FaceID + Access to the mobile phone number originally used for the app activation
Note: In the above cases (A, B) you will always be able to reactivate / transfer the IBKR Mobile Authentication (IB Key) when you possess an additional physical security device currently active for your user. With this setup, you will not need to have access to the mobile phone number originally used for the app activation, since the system will automatically prompt you to operate your physical security device instead of sending you a text message (SMS) during the reactivation / transfer procedure.

    In any other case, we would kindly ask you to request a temporary account access by contacting IBKR Client Services (Secure Login department) on the phone number best suitable for your location, among the ones listed on

Mobile Phone Verification during the account application


IB requires that clients verify their mobile phone in order to receive account and trade related communication directly via SMS.  Clients who fail to verify their phone will be subject to trade restrictions pending completion of this process. Verification is performed online and the steps for doing so are outlined below.
In case your account has been already opened but your mobile number has not been yet verified, please jump directly to KB2552 to complete the verification process.


Phone Verification

When completing your Interactive Brokers Account Application, you will see a blue bar at the top of the page that says "CONFIRM MOBILE NUMBER."

You can click on that bar any time during steps 1-4.   Once you do, you will see this window:

Once you have entered your full number, it will be recognized and a confirmation message is sent immediately.  Validate your phone number by entering the SMS Code received in the Confirmation Code field and click Submit.

If you are unable to do this during the application process, you can always confirm it on the Application Status page


Please consider the following as certain restrictions may apply:

  • SMS messages may be blocked if you participate in your Countries NDNC (National Do Not Call) registry.
  • Due to fraud prevention measures, virtual number providers may be blocked.
  • Some carriers may restrict the Hours of delivery for SMS messages.


Multiple 2-Factor System (M2FS)


This page covers specific points on what the Multiple 2-Factor System (M2FS) is and how it functions. For general questions on the Secure Login System, please refer to KB1131.


Table of contents


What is M2FS?

M2FS allows any client to maintain more than one active security device at the same time. You no longer need to choose between a physical security device and the IBKR Mobile app as either can be used interchangeably. If you already possess an active security device, any further device activation will result in both devices remaining simultaneously active.


Back to top 



In case you currently use the Security Code Card / Digital Security Card+: if you use a physical security device, you may download and activate the IBKR Mobile app. Please refer to the directions for Android and iOS.

In case you currently use the IBKR Mobile app: If you use the IBKR Mobile app and have an account with a balance equal or greater than USD 500K, you qualify for the Digital Security Card+ . You may log in to Client Portal and request the DSC+ by following the instructions here.


Back to top  


Once you have both a physical device and the IBKR Mobile app enabled, M2FS is represented by a drop-down menu upon login. You can now choose the device you wish to authenticate with, following the below steps:

1. Enter your username and password into the trading platform or Client Portal login screen and click Login. If the credentials have been accepted, a drop down will appear, allowing you to Select Second Factor Device. If you log in to the TWS, please notice that the M2FS is supported from version 966.


Client Portal:


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 the second factor authentication succeeds, the Log-in will now automatically proceed.

Withdrawal limits

The device used to authenticate your withdrawal will define your withdrawal limits, according to the below table:

Security Device
used for Withdrawal

Maximum Withdrawal
Per Day

Maximum Withdrawal
in Five Business Days

Security Code Card1 USD 200,000 USD 600,000
IBKR Mobile app USD 200,000 USD 600,000
Digital Security Card1 USD 1,000,000 USD 1,500,000
Digital Security Card+ Unlimited Unlimited
Gold Device1 Unlimited Unlimited
Platinum Device1 Unlimited Unlimited

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

Example: You have both the IBKR Mobile app and the Digital Security Card+ enabled and you need to withdrawal more than USD 200K. You can use either device to login to Client Portal but you will be required to use the Digital Security Card+ to confirm your withdrawal request.

M2FS provides even more flexibility to IBKR'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.

IBKR Mobile Authentication as a Two-Factor Solution


At IBKR, we are committed to protecting your account through the use of 2-Factor log in protection. With 2-factor protection, account access is provided through use of "Something you Know" (i.e. entry of user name and password combination) along with "Something you Have" (i.e., a tool which generates a random code to be entered after the user name and password).  This 2-Factor protection is intended to mitigate the risk of online hackers (who've acquired your password via malware or social engineering) accessing your account.

While IBKR offers multiple 2-Factor options, IBKR Mobile Authentication is generally viewed as the most convenient to access and operate. Outlined below are some of the convenience factors offered by this app.


1. Always Available: 
Your smartphone is always with you, as well as your tool to grant you secure access to your IBKR account.

2. Convenient:
No additional devices to carry, track and watch out for. In the event of loss or change of phone, IBKR Client Services can assist you to get the app back up and running at a moment’s notice.

3. Quick Activation:
A couple of minutes within the download of the app, you can already use it to authenticate into your account.

4. No Shipping, Delivery or Return:
No delivery delays, no return of devices with depleted batteries. A quick download suffices.

5. Secure, but quick and No-Hassle Login with our Seamless Authentication:
When logging into the Trading Platforms or the Client Portal, you only need to enter your username and password - IBKR will send you a notification and you will use the IB Key protocol to complete the authentication, via your mobile biometrics or PIN, depending on your configuration.

6. Allows for multiple users to authenticate with the same app:
If you have one security device for your personal IBKR account, one for your joint account with your spouse and one for your business account you will be happy to know that you can activate the same app for all those users (and more).

7. Available for every smartphone, everywhere:
IBKR Mobile can be downloaded from the Apple App Store if you have an iPhone. Android phone users can get the app as usual from the Google Play store. Clients in China can obtain the application on both Baidu and the stores.

8. Works even Offline:
Should your phone be offline (e.g. when on vacation or with a bad reception), you can still use IBKR Mobile Authentication. Even though Seamless Authentication won't be accessible, the application can generate the codes you need to access your account and trade.

9. Secure delivery for your Password Reset:
With IBKR Mobile installed and the IB Key authentication activated, you can have the IBKR Client Services send you a temporary password to your phone in a secure way without exposing it through text messages and other means of communication.

10. Small footprint:

IBKR Mobile can be downloaded even on the most restrictive data plans and be installed on your smartphone without hogging resources. The application size and its operational use of resources are limited to the absolute minimum, while not compromising on its security.


For a general overview of IBKR Mobile Authentication including installation, activation and operation, please see KB2260.
