If you aren't comfortable with that you better not use any fintech apps like Cash App, Venmo, Wealthfront, Robinhood, any Intuit products, etc. These services use Plaid (like this app does) or similar APIs like Quovo, Yodlee, etc. Even financial institutions themselves like Citi Bank, American Express, Chime, PayPal, etc use these APIs to link your accounts.
And to be clear, the app itself never has access to your credentials. This all happens in an iframe that tokenizes your credentials.
