Hi, I’ve been trying to connect my bank to Quickbook and it gets to the part where it redirects to intuit data it’s had an error: Authentication failed INPUT

Good day, uservictoria-cornwel.

Which bank are you trying to connect to? Did you encounter any specific errors? Your bank’s connection may be interrupted for any of the following reasons:

• If there is a minor or major update in your bank information such as the bank account number.
• Update in your Online Banking Login credentials.
• Bank outage and other scheduled maintenance.

To get this sorted out, as an initial step, you can log into your bank account and check if there's information that you need to update. Once done, let's try to reconnect your account using the bank's URL.

1. Go to the Settings ⚙ icon, and then select Bank accounts.
2. In the search box, enter the name or URL of your bank. Then select Continue. If you've already connected an account before, select Connect another.
3. Enter the sign-in info you use for your bank's website.
4. When you’re ready, select Connect securely.

You can go through this article for your reference in adding an account: Connect bank and credit card accounts to QuickBooks Self-Employed.

Once connected, QuickBooks will automatically download your most recent transactions. To help you manage and categorise your bank transactions, see these articles for your references:
