I was advised that I would reduce my plan cost by $10/mo. if I changed my payment method from credit to debit. I got part way through the process, when I was told that they use a company called Plaid and to input my banking info. I was asked to input my bank account number, which I did, then asked for my password, which I was told by my bank not to do.. Fortunately, I could choose an altenative option, the manual option, which did not request my bank password so chose this route.
I would like to know if requesting a bank password is legal, and if not, what action needs to be taken?
