Follow these steps to log in to your QuantConnect account with the CLI:

  1. Request your user-id and API token.
  2. Retrieve your user-id and API token from the email you registered on QuantConnect.
  3. Run lean login to log in to the CLI, and enter your user-id and token when prompted. This command opens an interactive wizard asking you for your user-id and API token.
    $ lean login

Log Out

Run lean logout to log out. This command removes the global configuration file containing your user Id and API token.

Check Account Status

Run lean whoami to see the name and email address of the user who is currently logged in.
