QuickBooks Error 103 – Causes, Symptoms, and Step-by-Step Solutions

QuickBooks Error 103 is a common online banking error that occurs when QuickBooks Online is unable to connect to your bank account due to incorrect or mismatched login credentials. This error usually appears while updating bank feeds and prevents transactions from downloading, causing interruptions in daily accounting activities.

What Is QuickBooks Error 103?

QuickBooks Error 103 indicates that the bank server has rejected the login attempt made by QuickBooks. This typically happens when the username or password stored in QuickBooks does not match the credentials required by the bank. Even if you can log in successfully on the bank’s website, outdated or incorrect credentials saved in QuickBooks can still trigger this error.

Common Symptoms of QuickBooks Error 103

Users experiencing this error may notice the following signs:

• Bank transactions not downloading
• Error 103 message during bank feed update
• Bank account marked as “needs attention”
• Repeated prompts to update bank credentials
• Interrupted automatic bank synchronization

Why Does QuickBooks Error 103 Occur?

Several factors can cause QuickBooks Error 103, including:

1. Incorrect Bank Login Credentials

Entering an incorrect username or password in QuickBooks is the most common reason for this error.

2. Recently Changed Bank Password

If you recently updated your bank password, QuickBooks may still be using the old login details.

3. Bank Account Locked or Restricted

Multiple failed login attempts can temporarily lock the bank account, preventing QuickBooks from accessing it.

4. Additional Security Requirements

Some banks require security questions, OTPs, or CAPTCHA verification that QuickBooks cannot process automatically.

Follow these steps to resolve the issue safely:

Step 1: Verify Bank Credentials

Log in directly to your bank’s official website and confirm that your username and password are correct and active.

Step 2: Update Credentials in QuickBooks

Sign in to QuickBooks Online, go to the Banking section, and update your bank login credentials carefully.

Step 3: Check for Bank Alerts or Notifications

Review any security messages or alerts on the bank’s website and complete required verification steps.

Step 4: Wait If Account Is Locked

If your bank account is temporarily locked, wait for the lock period to expire or contact your bank for assistance.

Step 5: Refresh Bank Feeds

After correcting credentials, return to QuickBooks and manually update the bank feed.

Tips to Prevent QuickBooks Error 103

• Update bank credentials immediately after changing passwords
• Avoid multiple failed login attempts
• Monitor bank security alerts regularly
• Use a secure and stable internet connection

When to Contact Support

If QuickBooks Error 103 persists even after entering correct credentials and resolving bank alerts, the issue may be related to bank-side security restrictions or account configuration problems. In such cases, contacting QuickBooks support can help restore uninterrupted bank feeds.
