How does Quantopian connect to IB?

Doesn't IB require a local TWS connection as well as credentials, e.g. 2-factor authentication?

We run an IB gateway and in the Quantopian UI you enter your IB credentials - but we do not store your password. You then deploy your algo and see a dashboard with updates from the market.
