QuickBooks Error 103: Expert Fix for Bank Login Rejection

You open QuickBooks Online to download the latest bank transactions. Instead of new activity, you see: "We're having trouble connecting to your bank. Error code: 103" Or perhaps: "The username or password you entered is incorrect."

The bank feed stops. New transactions do not download. Your reconciliation is blocked.

As a QuickBooks ProAdvisor, I have resolved QuickBooks Error 103 for businesses of every size. The good news: Error 103 has a specific, identifiable cause—and the fix is usually straightforward. The error almost always means the username or password stored in QuickBooks no longer matches what your bank expects . This guide explains exactly what Error 103 is, why it happens, and the proven steps to eliminate it.

What Is QuickBooks Error 103?

QuickBooks Error 103 is a bank connection error that occurs when the username or password QuickBooks has on file no longer matches what your bank expects. The error typically appears with a message like:

• "We're having trouble connecting to your bank. Error code: 103" or "The username or password you entered is incorrect."

• Critical distinction: Error 103 is a credential rejection error. Your bank has actively rejected the login attempt because the credentials are wrong, expired, or outdated . This is different from Error 102 (bank server down) or Error 105 (bank server not responding as expected).

Your financial data is safe. Error 103 does not corrupt or delete any existing transactions in QuickBooks. Only the connection to your bank is blocked .

Error 103 belongs to the bank feed error series (101, 102, 103, 105, 106), all of which relate to connectivity between QuickBooks and your financial institution .

Quick Summary

Why QuickBooks Error 103 Occurs

Understanding the root cause helps you fix it correctly the first time. Error 103 stems from QuickBooks' inability to authenticate with your bank. Common causes include :

1. Password Changed at the Bank

You changed your online banking password but did not update it in QuickBooks. The old password stored in QuickBooks is now invalid, and the bank rejects the connection .

2. Browser Autofill Entering Old Credentials

Your browser has saved an old password for the bank's website and is auto-filling it into QuickBooks' connection fields. Even if you think you are typing the correct password, autofill may override it .

3. Bank Security Updates

Your bank updated its authentication requirements—adding multi-factor authentication, changing login protocols, or requiring third-party access approval. QuickBooks cannot authenticate with the old method .

4. Account Locked After Failed Attempts

Multiple failed login attempts (from autofill or old credentials) may have locked your bank account. Until the lock is cleared on the bank's website, no connection will succeed .

5. Third-Party Access Disabled

Some banks block third-party apps like QuickBooks unless you explicitly enable access in your online banking settings .

6. Wrong Bank Selected in QuickBooks

If you selected the wrong bank listing (e.g., a different region or a similarly named institution), the credentials won't match .

How Error 103 Shows Up: Symptoms to Recognize

Before applying fixes, confirm you are dealing with Error 103. The symptoms typically include :

• Error message on screen: "We're having trouble connecting to your bank. Error code: 103" or "The username or password you entered is incorrect"

• Bank feed stops updating: New transactions do not download

• Repeated login prompts: QuickBooks keeps asking you to re-enter credentials

• You can still log into your bank directly: This is the most telling symptom—if your bank's website works but QuickBooks cannot connect, the issue is the stored credentials

• Only one specific account fails: Other bank connections work normally

QuickBooks Error 103: Expert Troubleshooting Steps

Follow these steps in order. Step 2 (Re-enter Credentials) resolves the majority of Error 103 cases. Start with Step 1 to confirm the problem, then proceed.

Step 1: Verify Your Credentials on the Bank's Website

Before changing anything in QuickBooks, confirm your credentials actually work .

Steps:

• Open a new browser window (not incognito yet).

• Go to your bank's official website directly.

• Sign in using the same credentials you want to use in QuickBooks.

• In case your password is auto-filled, click the eye icon to view it and confirm it is correct .

• If you cannot log in, reset your password on the bank's website first.

• If you can log in, proceed to Step 2.

Step 2: Re-enter Credentials in QuickBooks (Primary Fix)

This is the fastest and most effective fix for Error 103 .

Steps:

• Go to Banking > Bank transactions .

• Locate the card for the account that generated Error 103.

• Click Edit (✎) .

• Tap Edit sign-in info .

• Clear any auto-filled fields completely .

• Manually type your current bank username and password.

• Complete any MFA verification if prompted.

• Click Update .

Important: Do not let your browser auto-fill the credentials. Saved passwords are a common source of this error .

Step 3: Check for Bank Alerts or Required Actions

Your bank may be blocking the connection until you acknowledge a notification .

Steps:

• Log into your bank's website directly.

• Look for alerts, messages, or notifications on your account.

• Check for new security requirements (MFA, security questions, terms updates).

• Check if your bank requires third-party access to be enabled .

• Clear any prompts the bank is showing you.

• Return to QuickBooks and run a manual update.

Step 4: Try Reconnecting with a Different Bank Listing

If the credentials are correct but Error 103 persists, you may have selected the wrong bank listing in QuickBooks .

Steps:

• In QuickBooks, go to Banking > Bank transactions.

• Click Add account or Link account .

• Enter your bank's name or URL.

• If multiple listings appear for your bank, try a different listing .

• Enter your correct credentials and click Connect Securely.

• If that listing fails, go back and try the next one.

Step 5: Clear Browser Cache and Cookies

Accumulated cache can interfere with bank connection authentication .

Steps:

• Open your browser settings.

• Navigate to Privacy or History settings.

• Select Clear browsing data.

• Check Cookies and Cached images and files.

• Select All time as the time range.

• Click Clear data.

• Restart your browser and log back into QuickBooks Online.

Step 6: Disconnect and Reconnect the Bank Feed

If the error persists after updating credentials, the connection itself may need to be re-established .

Steps:

• Go to Banking > Banking.

• Click the affected bank account.

• Select Edit > Edit account info.

• Check Disconnect this account on save .

• Click Save and Close.

• Click Add account or Link account and search for your bank again .

• Reconnect using your current bank credentials.

Important: When QuickBooks asks which account to link, choose the account already in your chart of accounts. Creating a new one is the most common way owners end up with duplicate accounts.

Step 7: Use Incognito/Private Browser

If the error persists, your browser's saved data may be interfering .

Steps:

• Open an incognito/private window (Chrome/Edge: Ctrl+Shift+N, Firefox: Ctrl+Shift+P).

• Log into QuickBooks Online.

• Try reconnecting the bank account from the incognito window .

• If it works, the issue is your regular browser's cache or saved passwords.

Error 103 vs. Error 102 and Error 105: What Is the Difference?

The key distinction: Error 103 requires active steps to update credentials. Errors 102 and 105 may resolve on their own with time .

Real-World Example: Fixing Error 103 Before Month-End Close

A retail client contacted me on the last day of the month. Their QuickBooks Online bank feed displayed Error 103. They could not download October transactions, and month-end close was blocked.

Diagnosis: The client had changed their online banking password two weeks earlier but never updated it in QuickBooks. Their browser was also auto-filling the old password, creating confusion .

Steps Taken:

• Verified credentials worked on the bank's website directly .

• Went to Banking > Bank transactions, clicked Edit sign-in info on the affected account .

• Cleared the auto-filled fields and manually typed the current bank credentials .

• Completed MFA verification.

• Ran a manual update via Banking > Bank transactions > Update.

• All missing transactions downloaded successfully.

Result: Total resolution time: 12 minutes. The client completed month-end close on schedule.

Lesson: For Error 103, the fix is almost always updating the stored credentials. Browser autofill is a hidden culprit—always clear the fields and type manually .

How to Prevent QuickBooks Error 103

Prevention is simpler than repair. Follow these maintenance practices :

• Update bank credentials in QuickBooks immediately after any password change

• Disable browser autofill for your bank's website to prevent old passwords from being entered

• Respond to bank alerts promptly when they appear on your bank's website

• Check if your bank requires third-party access to be enabled

• Log in to your bank every few weeks to keep the connection fresh

• Clear browser cache periodically to prevent connection conflicts

• Use a supported browser (Chrome or Firefox) for QuickBooks Online
