Our bank has not been able to link with quickbooks for the past week. no one is helping us

This is not the impression we wish to leave you with, @louanneccs. 

Please know that I will be here every step of the way to ensure you have your bank connected to QuickBooks Online. 

Before we begin, I wanted to ask which bank you're currently using? This way, I can check if we have any ongoing investigations with that bank that might be causing the error message. 

Typically when we see error 103, the user ID or password is incorrect for that bank account you're trying to connect to. While I await your response, I've gone ahead and covered some basic troubleshooting steps to try below. 

First, let's ensure the user ID and password are correct.

1. Open a new window in your web browser and go directly to your bank's website.
2. Make a note of the web address (e.g. https://www.bank.com). This may come in handy later.
3. Sign in with the user ID and password you have.
4. If you sign in successfully, then you know the user ID and password are correct. If you get a sign-in error, follow your bank's instructions to get your user ID, reset your password, or both.

If you log in successfully from the bank's website, let's check if your bank requires a third party sign on. Please know these steps may differ depending on your bank. 
 

1. Sign in to the account you want to connect to QuickBooks.
2. Select User Profile.
3. In the Password and Security section, switch on Third Party Access.
4. Select Yes to confirm your choice. 

Once the third-party access has been turned on, try connecting the account to QuickBooks Online again. 

Let me know how it goes. I'm here if you have any additional questions or concerns. Have a good one!
