Intuit provides reliable data access to millions of customers

As a well-known provider of financial management software such as Mint and Quickbooks, Intuit needed a more streamlined and reliable way to provide users access to their data without storing credentials.

Using Citi’s authentication technology and Accounts APIs, customers can now authorize Intuit to reliably access their Citi account data—such as balances, due dates and transaction history. Customers can then view their data through engaging infographics and charts.

By partnering with Citi, Intuit can provide accurate and up-to-date information for a better customer experience.
