I'm here to help get your online banking to reconnect so you can start downloading transactions.
When you recently change your online banking credentials, you'll also have to update the bank information in QuickBooks. You can click the Edit sign ininfo button to change the bank's password. Let me show you how:
Go to the Transactions menu and then select Banking.
Select the tile for the bank account.
Click the Edit ✎ next to the bank name then, select Edit sign-in info.
Enter your updated bank password.
Hit Save and connect.
Once you see a confirmation message, click I'm done, Let's go!
Utilize the trial version of MT Online to isolate the issue. It is designed to import into any bank or credit card in QuickBooks Online, so there is no specific setting needed. If the same error persists, there is an ongoing problem at your bank or connection.
