Hi there info1700,
It's great that you're trying to connect your banks to your QuickBooks Online account. It's a great feature that can save you time with data entry in your books so that you can spend more time running your business. I can provide some information about bank connections and multi-factor authentication.
Two-step verification is a security measure offered by banks in order to prevent anyone other than yourself to access information on your bank account. This prevents unauthorized access to your bank account as well as other automated services from being able to connect to your bank as well. This does prevent QuickBooks from being able to connect, due to it being an automated service, and the code needed to get through this two-step authentication can't be sent to Quickbooks. In order to be able to connect your bank accounts to QuickBooks Online to import transactions directly, this security measure would need to be deactivated for your account on your bank's website.
If you want to keep that measure active on your bank account, you can import your bank transactions through different file types such as .csv files and .qbo (QuickBooks) file extension among others. If you were to want to explore that option, you can find the steps on how to manually upload transactions into QuickBooks Online by clicking on the provided link.
If you have any other questions, feel free to reach out here.
