Secure Login System (SLS)

To provide you with the highest level of security, Interactive Brokers uses a Secure Login System (SLS) with two-factor authentication (2FA) to help protect your account.

Two-factor authentication serves to confirm your identity at the point of login by using two security elements:

  • Your username and password combination (e.g., something you know)

  • Your mobile device or, in some instances, an IBKR issued security device (e.g., something you have)

Because the SLS requires both elements, the risk of someone other than you accessing your account is greatly reduced.


Two-Factor Authentication via the Secure Login System offers several benefits, including:

  • Always available: Your smartphone is always with you and serves as the tool to grant secure access to your IBKR account.

  • Convenient: No additional devices needed. In the event of loss or change of phone, IBKR Client Services is available to help you get the app back up and running at a moment’s notice.

  • Quick activation: Once downloaded and setup, you can immediately start using the app to securely access your account.

  • No shipping, delivery, or return: No delivery delays or need to return a device with depleted batteries.

  • Secure, but quick and “no-hassle” login: When logging in to our Trading Platforms or Portal, enter your username and password. We will send you a notification and you will use the IB Key feature within IBKR Mobile to complete the authentication.

  • Allows access for multiple users: Each user associated with your account can install IBKR Mobile to securely access the account.

  • Available for every smartphone, everywhere: IBKR Mobile is available for download to any mobile device. Users of Apple iPhone can download the app from the App Store. Users of Android phones (e.g., Samsung, Google, Motorola, Asus, Xiaomi, One Plus, etc.) can download the app from the Google Play store. Clients in China can download the application from the Baidu and stores.

  • Works offline: If your device is offline (e.g., no signal), you can still use IBKR Mobile to authenticate. The application will generate the codes that you need to access your account and trade.

  • Secure delivery for password resets: With IBKR Mobile installed and the IB Key authentication configured, IBKR Client Services can securely send a temporary password to your phone without exposing it through text messages and less secure communication channels.

  • Small footprint: IBKR Mobile can be downloaded and used on even the most restrictive data plans. The app’s size and use of resources is limited to the absolute minimum.

Note: All IBKR accounts are required to enroll in two-factor authentication.
