Solution 1: Verify Your Bank Login Credentials

Incorrect bank login credentials cause most QuickBooks Online Banking Error 103 issues. First, confirm that the username and password stored in QuickBooks match the credentials you registered with your bank. To verify your credentials, follow these steps:

• Open QuickBooks Online and select Verify your credentials from the Error 103 message.

• Sign in to your bank account.
• Reset your username or password on the bank website if the login fails.
• Return to QuickBooks after confirming your credentials.

Note: Choose the correct account when your bank provides separate personal and business logins.

QuickBooks Self-Employed users follow a slightly different process to resolve Error 103.

• Click Reconnect from the Error 103 message.

Note: Some banks require you to enable third-party application access from your online banking security settings before QuickBooks can reconnect successfully.

Solution 3: Update Your Bank Sign-in Information in QuickBooks Online

After verifying your bank credentials, update the same information in QuickBooks. You can update an existing bank connection or create a new one.

Option A: Update an Existing Bank Connection

• Sign in to QuickBooks Online.
• Open Transactions and select Bank Transactions.
• Choose the affected bank or credit card account.
• Click Edit and select Edit sign-in info.
• Remove any auto-filled username or password.
• Enter your latest bank login credentials manually.
• Review the information and click Update.
• QuickBooks attempts to reconnect using the updated credentials.

Option B: Create a New Bank Connection

Create a new connection when updating the existing one does not resolve the error.

• Open Transactions and select Bank Transactions.
• Click Link account. Select Connect account when connecting a bank for the first time.
• Search for your bank by entering its name or official website address.
• Select the appropriate bank from the search results.
• Choose the correct account type, such as Business or Personal.
• Remove any auto-filled login details.
• Enter your latest bank username and password manually.
• Click Continue and wait for QuickBooks to establish the connection.
• Repeat the process with another bank listing when multiple options appear, and the connection fails.

Solution 4: Disconnect the Existing Bank Connection

• Choose the affected bank account.
• Click Edit and select Edit account info.

• Click Save to complete the process.

Reconnect the bank account after disconnecting it and verify that transactions download correctly.

Solution 5: Enable Third-Party Access for Your Bank Account

Some banks block third-party applications, including QuickBooks, until you grant permission. Third-party access allows QuickBooks to communicate with your bank and download transactions successfully.

• Open your bank’s official website and sign in to your account.
• Navigate to your account’s Security, Privacy, or Connected Apps settings.
• Look for an option related to Third-Party Access, External Applications, or Connected Apps.

• Save the changes and sign out of your bank account.
• Return to QuickBooks Online and refresh your bank connection.
• Note: The location and name of this setting vary by bank. Contact your bank when you cannot find the option.

Solution 6: Resolve Security Verification Issues

Failed login attempts or browser-related issues sometimes trigger additional security verification, which prevents QuickBooks from connect to your bank. A private browser session often resolves this problem.

• Open a private or incognito browser window.
• Visit your bank’s official website.
• Sign in using your current username and password.
• Complete any security questions, one-time password (OTP), or identity verification requested by your bank.
• Confirm that you are signing in to the correct online banking portal for your account.
• Close the private browser window after successful verification.
• Open QuickBooks Online and update your bank connection again.
• QuickBooks verifies your account successfully and restores the banking connection.

Note: Continue with the correct bank listing in QuickBooks. Some banks offer separate connections for personal and business accounts. Selection of the wrong one may trigger Error 103.
