Well of course I won't use anything like that! I find it mind-boggling that people even consider giving a third party their bank account login+password. It's like saying "yes, I want to be robbed of all my money, please take these credentials and spread them forth to whichever leaked data pile they might end up in".
My bank considers transactions done using login credentials to be final. There is no recourse if someone steals your money.
Last year an iOS mail application called "Spark" (otherwise a great app) decided to quietly upload my login and password to their cloud servers so that their servers can access my mail for me. I dropped the app immediately (https://jan.rychter.com/enblog/spark-email-app-why-i-dont-us...).
This should not be considered acceptable. If you want to let users authorize external access to account data, use Oauth2.
