In Europe there are legitimate and extremely established services that require you to input your bank login details into something other than your bank's website. It's madness.
PSD2 is just MFA, it doesn't prevent shady companies still asking your login credentials, even if you must authorize that login from your official banking app. Klarna is one of many examples - they ask me for my bank credentials on their own website so they can crawl all my finance data .
Plaid and Finicity do this in the USA for some linking of banking to other financial products. Feels SO insecure. Connecting my credit union checking account through Plaid even ironically brought me to a login page which explicitly states I should never give my banking password to any other entity.
If I need to link my accounts and these services are the only choice then I change my banking passwords immediately after.
Plaid whole business model is that it uses OAuth2 on banks that support it and export the data through APIs; and for the banks that don't, they ask for name/password and scrape it through "fake" web browser that mimick user behavior on the backend.
(I worked for a Plaid competitor. The long-term goal for all similar companies is of course to use OAuth and APIs, because it breaks less often; but since the banks don't offer that, scraping it is!)
I have a Klarna account I opened when their flex account rate was amongst the best you could get and I don't remember them ever asking for my bank credential.
I think Bankin' used to before PSD2 and to get a bit more information from some banks but then again Bankin' is a financial agreggator whose explicit purpose is crawling your banking data so it's not too surprising to see them asking for your credentials.
Not sure what you mean specifically, but generally the organisations doing screen-scraping¹ would prefer to use compliant APIs as they don't require anything like as much maintenance (bank adds a button to the login flow? Kaboom! Integration is broken...) or resources (e.g. running headless browsers).
Some markets are pretty much exclusively compliant - I don't think there are any Nordic banks that don't have fully PSD2 compliant APIs for example whereas, if I remember rightly, the Spanish banks were all over the place. I'm fairly out of date though, so things may have improved or exceptions for scraping expired.
¹ Note that I'm talking exclusively about banking integrations here, not AI nonsense.
If you used the first gen "pay later" services they'd scrape you for "compliance checking" or simply mask it as a transaction which is actually just personal information scraping.
Most of the times you did not see it, as it's obfuscated as a part of the transaction.
They are also the companies complaining a lot about the "failure" of the PSD standards since it limits how much and how obfuscated they can scrape everything (and there are records).
