Investing platforms

I am trying to find an investing platform (Robinhood, Fidelity, Schwab, etc) that does not require I use a 3rd party servicer to fund the account.

I have major concerns about any service that requires I give my username and password for my bank account.

I’ve ruled out Robinhood, Fidelity and WeBull. I have no problem providing a PayPal/venmo/apple account but something about giving my password to my checking account makes me very uncomfortable.
