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 uses Plaid and Tradeit to link your broker account. Plaid and Tradeit are aggregation providers that sits between kinfo and broker and provides the necessary security infrastructure to connect to every broker in a secure manner.
When you press the link button you will be presented with a form from either Plaid or Tradeit where you enter your credentials. The kinfo platform doesn´t control or have access to this form. This is an important security feature since it means that kinfo will never be able to see your credentials.
When you have authenticated, kinfo will receive a token that can be used to import transactions and holdings to perform calculations of trading performance metrics.
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. Tradeit is not as large as Plaid but still a well known and trusted provider of secure communication between apps and brokers. Plaid is currently owned by Visa and Tradeit is owned by Tradingview.
By using Plaid and Tradeit 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, Tradeit and the broker uses bank-level 256-bit encryption
- The token used by kinfo can only be used to read data, never make changes or execute trades

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.
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.
