Plaid just settled a $58 million class action lawsuit for a) collecting people’s usernames and passwords then b) scraping their transaction history without their consent and selling it to data brokers.

From the complaint:

4. First, Plaid induces consumers to hand over their private bank login credentials to Plaid by making it appear those credentials are being communicated directly to consumers’ banks. Consumers are informed the connection is “private” and “secure,” and their banking credentials will “never be made accessible” to the app. They are then directed to a login screen that looks like it is coming from their bank, complete with the bank’s logo and branding. In reality, however, though Plaid does not disclose this, the login screen is created by, controlled by, and connected to Plaid. Plaid executives have acknowledged this process was “optimized” to increase “user conversions”—in other words, to provide a false sense of comfort to consumers by concealing Plaid’s role as an unaffiliated third party.

5. Second, Plaid uses consumers’ login credentials to obtain direct and full access to consumers’ personal financial banking information for Plaid’s own commercial purposes wholly unrelated to consumers’ use of the apps. For each consumer, Plaid downloads years’ worth of transaction history for every single account they have connected to that bank (such as checking, savings, credit card, and brokerage accounts), regardless of whether the data in any of the accounts bears any relationship to the app for which the consumer signed up. Thus, a consumer who makes a single mobile payment on an app from a checking account unwittingly gives Plaid years’ worth of private, granular financial information from every account the consumer maintains with the bank, including accounts maintained for others such as relatives and children. To date, Plaid has amassed this trove of data from over 200 million distinct financial accounts.

6. Plaid exploits its ill-gotten information in a variety of ways, including marketing the data to its app customers, analyzing the data to derive insights into consumer behavior, and, most recently, selling its collection of data to Visa as part of a multi-billion dollar acquisition. Plaid has unfairly benefited from the personal information of millions of Americans and wrongfully intruded upon their private financial affairs.
