You can use the Plaid Portal (https://my.plaid.com) to view what types of data are being shared, to revoke access (to both the apps and Plaid) and delete data stored in Plaid’s systems. You can also put a data deletion request through support.

Not as per my comment above that we don’t, and have not, sold data. https://plaid.com/legal/#consumer-support

I have tried to login to this site, registered my phone number, and it says it can't find any accounts of mine. yet I know YNAB uses plaid as its backend, and has links to my banks, credit card companies, and even my mortgage.

Is this a bug, or are those of use that use certain 3rd parties not able to see our data?

Would love to help with this. YNAB hasn't always been a Plaid customer, so it might have been a historical connection -- either way, please contact our support team to help you figure this out ASAP https://my.plaid.com/help

You have customers that use consumer data and they don't have to pay for it? Where can I get this free data?

Why did you settle for $58M in fines when Yodlee does the same thing but they very blatantly sell customer data, and as of yet, remain untouchable?

Visibility in my opinion.

Plaid is a financially juicy target that has a lot of customers.

I did this recently (well not all my data, but one bank account). I had to go through customer support, and they had some trouble with it but eventually figured it out.

I'm not a fan of Plaid. The core concept is great, but training users to enter credentials (much less banking credentials) into third-party sites is nuts. Nowadays, it would be easy for someone to pivot from a compromise of a random company's web server to impersonating Plaid and pwning most of their customers' bank accounts.

This would be trivial to fix by deprecating their current UI and switching to a small popup or redirecting to a different URL.

If you change your bank credentials, at least your current data is safe. You mean how to delete the data they scraped?
