I came across Plaid for the first time today and when trying to make a transfer through Transferwise. When asked for my bank username and password at a website !my_bank I was like hell nope. Ended up having to use a credit card instead which had the highest fee... :( I hope this kind of garbage disappears.
I would rather have entered my logins and then changed the password if I was that concerned about entering my bank logins rather than pay those credit card fees. Or change the password first, login, and change back to your old password.
If you're happy to hand out your credit card details to Plaid and trust them enough to properly secure it, personally I wouldn't be concerned about them flagrantly and illegally retrieving my past transactions. There is no such thing as trust less financial services that deal with fiat currency.
