I want to stop this issue from happening to you, Stephanie.
There's a possibility that you mark the Remember me box when you log in to your QuickBooks account. That's why it won't accept your bank's credentials.
Let's work together by clearing saved usernames and passwords on the browser. Doing this will help you enter the correct credentials and download transactions from your bank.
Please follow the steps to delete usernames and passwords for your browser.
Once done, restart your browser for changes to take effect. When you log into QuickBooks, make sure to uncheck the Remember me box.
This prevents the browser from saving login credentials and helps you enter the correct username. You can also use a private window or other supported browsers to isolate the issue.
If the same issue persists, I recommend contacting our QuickBooks Live Support Team. They further investigate why the username of your bank keeps using the QuickBooks credentials.
Please know I'm always here to answer your questions about the Online Banking feature and other processes in QuickBooks. Just reply here, and I'll hop on to this thread again.
