Linking your broker

Supported brokers

Kinfo supports most US brokers including the big brokerages such as Robinhood, Interactive brokers, TradeSation, TD Ameritrade, Fidelity, E* Trade, Ally and Charles Schwab. We are continuously adding support for new brokers and the goal is to support all brokers in the US.

How does it work?

Kinfo has direct integration to a number of brokers and uses Plaid for non direct integrated brokers. Plaid is an aggregation provider that sits between kinfo and broker and provides the necessary security infrastructure to connect to every broker in a secure manner.

Direct integrated broker either uses Oauth to provide a three-legged authentication process between the broker and kinfo, or it uses less sensitive credentials that can only be used to read data, this is the case when linking via clearing firms.

Linking via Plaid is an oath type process whereyou are presented via a form from Plaid. When the linking process is finished, kinfo will obtain a token from plaid which can be used to read data.

You can read more about the process under the guide for each broker.

About security

Kinfo uses best-in-class solutions for all technology, software and infrastructure used to link brokers with the kinfo platform. Plaid which is the worlds biggest aggregation provider is trusted by thousands of personal finance and investing apps.

Kinfo is required to follow certain specifications to achieve a high level of security. The most important of these are:

  • Kinfo NEVER see, store or have access to your real broker credentials
  • Kinfo can NEVER be used to execute trades
  • Kinfo can NEVER touch your money/assets or make any changes to your account
  • All communication between the  app, kinfo, Plaid, and brokers uses bank-level 256-bit encryption
  • The token used by kinfo can only be used to read data, never make changes or execute trades

For more in-depth information, see our page about security.

What about MFA?

MFA stands for multi-factor-authentication and is an extra security measure brokers use to verify new devices that try to authenticate with a user’s credentials. 

In some cases, a link to a new broker will trigger MFA authentication. When this happens you have to login to your account on kinfo and update your account. Brokers behave differently but in most cases, your should only be required to do this once.

The linking process

The linking process works the same way independent if you are using the kinfo app or the web app. When you have successfully authenticated with your broker, kinfo will start downloading transactions and calculate trading performance metrics.

This process may take a minute to complete, once it´s done you will receive a notification and the app will update automatically.

Some brokers require a few extra steps to get linking working properly, see the following detailed guides:

Transaction history

When linking your broker, trading performance will be calculated from inception and going forward. Dependent on the broker you will also get performance metrics calculated retroactively. 

Sharing

Being able to share is a valuable part of the kinfo platform and one of the main reasons users join. While we want everyone to share their metrics it´s completely optional.

By default, you will share non-sensitive data based on percentages without any dollar amounts. This includes average gain on trades and winning trades in percent. If you are uncertain about how these metrics are calculated, please read about How trading metrics are calculated.

If you chose to share dollar amounts, you will share gain in dollar on each trade and accumulated profit based on closed out trades.

In no cases will account size or account numbers be shared.
