Trying to connect your bank account to QuickBooks Online but suddenly getting stuck with QuickBooks Error 103 can be frustrating. This error occurs when QuickBooks cannot verify your banking login credentials or access your account information.
It can prevent you from connecting your bank account or downloading recent transactions in QuickBooks Online. The good news is that this bank connection error can be fixed by checking your login credentials or updating your banking connection.
In this guide, we’ll explain what QuickBooks Error 103 means, why it occurs, and walk you through practical steps to fix it.
QuickBooks Error Code 103 is a bank authentication error. It specifically means that QuickBooks Online has attempted to connect to your bank using the credentials stored in the bank connection settings and the bank has rejected them either because the username or password is wrong, because the bank requires a verification step before granting access, or because the bank’s login process has changed.
Error Code 103 in QuickBooks Online means the bank has returned an authentication failure in response to QuickBooks’s connection attempt. The bank received the connection request but could not validate the credentials so it rejected access to the account’s transaction data. The result is that the bank feed stops updating and no new transactions are imported until the credentials issue is resolved.
This is different from errors that occur because the bank is unavailable. With QuickBooks Online Error 103, the bank is reachable; it is actively rejecting the login, not failing to respond. That distinction is important because it tells you exactly where to look: not at the bank’s server status or your internet connection, but at the username and password stored in QuickBooks for that bank account.
What Does the QuickBooks Error Message 103 Mean?
The QuickBooks error message 103 typically appears on the Banking page alongside the affected account and reads something like: “We’re having trouble connecting to your bank. Your sign-in info might be wrong. Please update your bank’s sign-in info (103).” The message is directing you to the correct fix. The sign-in information stored in QuickBooks needs to be reviewed and updated. Before updating anything in QuickBooks, however, the first step is always to confirm whether the credentials are actually wrong by testing them on the bank’s own website.
Yes, QuickBooks bank connection error 103 is classified as a bank feed authentication error. It is one of a series of numbered banking errors in QuickBooks Online (including 102, 105, 106, and 108) that each indicate a specific type of connection problem. Error 103 is specifically the authentication error the credentials are wrong or rejected. It is not a general connectivity failure, a bank outage error, or an account-not-found error. If you are seeing Error 103, the bank connection itself is working; it is the login credentials that are the problem.
QuickBooks banking error 103 is almost always a credentials issue, but there are several different reasons why credentials can fail. Understanding the specific cause helps you pick the right fix without unnecessary steps.
Incorrect Bank Login Credentials
The most direct cause of QuickBooks online bank error 103 is that the username or password stored in the QuickBooks bank connection is wrong. This commonly happens when you have recently changed your online banking password and not updated it in QuickBooks. It can also happen if you typed the credentials incorrectly when first setting up the connection, or if your bank requires a username that is different from what you entered for example, a member ID rather than an email address.
Your Bank Requires Additional Verification
Many banks require periodic re-verification for third-party services that access account data. Your bank may be presenting a security prompt such as a two-factor authentication request, a terms-of-service update, or a security question that must be completed on the bank’s own website before data access is permitted. Until you complete this verification, the bank will reject QuickBooks’s connection attempt and return Error 103.
QuickBooks Cannot Connect to Your Bank
In some cases, QuickBooks online bank error 103 can appear when the connection between QuickBooks and your bank has become unstable or broken due to a session issue rather than a credentials change. This is less common but can occur after extended periods without a successful sync, or after an interrupted connection attempt.
Your Bank Has Changed Its Website or Login Process
Banks periodically update their online banking platforms. When a bank changes how users log in for example, introducing a new login URL, switching to an account number as the primary identifier, or adding mandatory multi-factor authentication the credentials stored in QuickBooks may no longer work even if your actual password has not changed. The login process itself has changed and QuickBooks needs to re-establish the connection using the updated process.
The Bank Connection in QuickBooks Is Outdated
The configuration QuickBooks uses to connect to a specific bank can become outdated if the bank updates its data feed infrastructure. In these cases, QuickBooks may be attempting to connect using an old connection pathway that the bank no longer supports, which can trigger credentials error even if they are correct. Reconnecting the bank account refreshes this configuration.
Browser Cache or Session Problems
Sometimes, your browser’s stored cache, cookies, or outdated login sessions can create problems when QuickBooks Online tries to connect with your bank. Even if you’ve entered the correct username & password, old session data may interrupt the authentication process and lead to QuickBooks Error 103. Clearing your browser cache & signing in again can help refresh the connection and resolve the issue.
Your Financial Institution Is Temporarily Unavailable
Though Error 103 is primarily a credentials error, a bank that is temporarily unavailable or running in a degraded state can sometimes return authentication errors rather than connection timeout errors. If you have confirmed your credentials are correct and the error appeared suddenly, checking whether your bank is experiencing a service disruption is a worthwhile step before troubleshooting the connection itself.
These quick checks are part of any sensible quickbooks error 103 troubleshooting process that takes a few minutes and will narrow down what needs to be fixed before you change anything in QuickBooks.
Confirm Your Bank Login Works Outside QuickBooks
Visit your bank’s official website and try logging in with your updated sign in credentials. If you fail to log in, check if your password has been changed or your username is correct. In that case, contact your bank to fix the login issue.
Furthermore, if you are able to access your bank account smoothly, it means the problem is due to the credentials saved in QuickBooks. You’ll need to update your banking login details in QuickBooks Online.
Check Your Bank’s Website
Once you are sign in to your bank account, check for any banners, alerts, or messages that require immediate attention on your bank’s website. Banks might display notifications regarding updated terms & conditions, security verifications, or new authentication requirements. If your bank is still showing any such prompt, then fix the error by completing the instructions given on your screen.
Confirm the Bank Account Is Active
Move to the specific account linked in QuickBooks and confirm it is active & showing transactions. A closed, frozen, or restricted account can produce authentication errors when QuickBooks attempts to access it.
Check for Bank Maintenance or Service Alerts
Check your bank’s website or its status page for any scheduled maintenance or service disruption notices. If the bank is in a maintenance window or experiencing an outage, the error will be fixed on its own without any changes needed in QuickBooks.
Open the Banking page in QuickBooks Online and check whether Error 103 appears for just one bank account or all your connected accounts. If the error affects only one account, it means that the issue is related to incorrect login details or an account-specific issue. However, if multiple accounts from the same bank show the error at the same time, the problem may be coming from the bank’s side or a recent change in its online banking system.
If the bank login works, the account is active, and no maintenance is scheduled to move to the fixes below. The QuickBooks error 103 how to resolve the path is clear: the connection needs to be updated or refreshed.
Fixing QuickBooks Online Banking Error 103 starts with identifying why QuickBooks cannot verify your bank account credentials. Follow the troubleshooting methods below to correct login issues, refresh your banking connection, and restore access to your bank transactions.
Before changing anything in QuickBooks, confirm that the credentials you are using are correct.
If you are able to log in successfully on your bank’s website, it shows that the credentials are correct. The issue is that QuickBooks has an older version of those credentials stored. Move to Fix 2.
Make note of the exact username format your bank uses some banks use an account number, a member ID, or an email address. Using the wrong format is a common cause of Error 103 even when the password is correct.
Once you know the correct credentials, update them in QuickBooks Online. This is the primary fix for QuickBooks Online Error 103 and QuickBooks Online bank error 103 caused by outdated or changed credentials.
If the manual update completes without QB Error 103, the fix is complete. If the error returns, the issue is not simply outdated credentials continue to the remaining fixes.
If the credentials are correct but QuickBooks is unable to authenticate, it means that the connection configuration for your bank in QuickBooks is outdated. Banks sometimes change the endpoint or the connection method QuickBooks uses to access them, and the existing connection no longer maps to the right login pathway.
To fix this, try removing the existing bank link and searching for the bank as if adding it for the first time.
Disconnecting and reconnecting is the most effective way to fix Error Code 103 when credential updates and reconnection searches have not resolved it. This re-establishes the entire bank connection from scratch. However, using the latest configuration for your bank rather than whatever connection existed before.
Before disconnecting: review and categories any pending transactions in the Banking tab. When you reconnect, QuickBooks may re-import recent transactions having your existing ones already reviewed and accepted reduces the cleanup after reconnection.
Disconnect the existing account
If reconnecting your bank account creates duplicate, uncategorized, or unmatched transactions, follow our guide to QuickBooks Online cleanup to review and organize your records.
Reconnect Bank Account:
What happens to existing transactions: transactions you have already reviewed and categorized in QuickBooks are not affected by disconnecting the bank account. They remain in your QuickBooks records. After reconnecting, QuickBooks will import transactions from the last 90 days (or fewer, depending on the bank) and may include some you have already reviewed these can be excluded or matched during the review step.
Even after reconnecting the account, Error 103 still exists, then check that the credentials you entered during reconnecting are correct. Apart from this, look whether your bank is showing any verification prompts which need to be completed on the website.
Sometimes, outdated browser cache and cookies can interfere with the connection between QuickBooks Online and your financial institution. This may prevent QuickBooks from verifying your banking details & can cause Error 103. Clearing your browser’s cache & cookies is a simple troubleshooting step that may help fix the problem.
If you are using a VPN or browser extension that modifies how your browser communicates with websites, temporarily disable it and test the bank update again. These tools can intercept or alter authentication requests in ways that cause Error 103.
If your bank needs additional verification, new terms & conditions, a security question, a two-factor authentication setup, or a re-authorisation of third-party data access. You need to complete the verification on your bank’s website. QuickBooks has no visibility into these pending prompts; it simply receives a rejected authentication response and displays Error 103.
Sign in to your bank’s online banking portal and look specifically for: notifications or alerts at the top of the page, messages in your inbox within the banking portal, prompts in account settings related to security or connected services, and any messages related to third-party data access or open banking. Completing any pending action here is one of the most effective ways to resolve QuickBooks Banking error 103 .
A weak or poor internet connection can cause authentication requests to time out or fail partway through, which QuickBooks may surface as Error 103 rather than a connectivity error. Make sure that your internet connection is stable.
While Error 103 is primarily a credentials error, a bank that is experiencing a service outage or scheduled maintenance can sometimes return authentication errors as part of its degraded-service behavior. Before spending more time troubleshooting the connection itself, check your bank’s website for maintenance notices or check a third-party service status site for reports of your bank being down. If the bank is in a maintenance window, wait for it to complete and then run a manual update in QuickBooks before taking further action.
QuickBooks banking error 103 is part of a broader set of bank feed issues in QuickBooks Online. This section explains the underlying connection behavior not the fixes, but why authentication failures happen and how the bank feed works when they do.
After resolving the bank connection issue and downloading your missing transactions, review your records and reconcile the imported entries using our guide to QuickBooks bank reconciliation.
QuickBooks Online connects to banks through a financial data aggregator a third-party service that handles the technical communication between QuickBooks and each bank’s data systems. When this aggregator attempts to authenticate with your bank and the bank returns an error, QuickBooks bank connection error 103 appears. The aggregator is doing exactly what it is supposed to do; the failure is at the bank’s authentication layer, not in QuickBooks itself.
When Error 103 is active, the authentication step of the bank feed process has failed and no new transactions are retrieved. Transactions that have been posted to your bank account after the error appeared are not lost they are simply not yet in QuickBooks. Once the credentials issue is resolved and a successful sync runs, QuickBooks will pull in all transactions from the last successful sync point.
If QuickBooks is repeatedly prompting you to re-enter your bank login details, it usually means the credentials previously entered are being rejected by the bank each time a sync is attempted. This is the most visible symptom of a persistent Error 103 situation. The loop of QuickBooks asking for credentials and the bank rejecting them will continue until either the correct credentials are entered, the required bank verification is completed, or the bank connection is refreshed through a reconnection.
A disconnect and reconnect (also described as a need to reconnect bank account in quickbooks online) is appropriate when: updating the credentials in the connection settings has not resolved Error 103, the bank has migrated to a new platform and the old connection configuration is incompatible, the error has been persistent for more than 24 hours despite the bank’s website working normally, or you want to reset the connection entirely to rule out a configuration-level issue. It is not necessary for errors that are clearly caused by a simple password change Fix 2 (updating login information) is sufficient for those cases.
QuickBooks error code 103 is one of several numbered bank errors in QuickBooks Online. Each has a distinct meaning. Knowing which error you have tells you where to look for the fix.
Error 102 means QuickBooks cannot establish any connection to the bank’s servers the bank is either down, under maintenance, or unreachable. Error 103 means the connection reached the bank but the bank rejected the login credentials. In practical terms: if QuickBooks cannot find your bank at all, it is Error 102. If QuickBooks reaches your bank but cannot log in, it is Error 103. The fix for Error 102 is to wait for the bank to restore service; the fix for Error 103 is to resolve the credentials issue.
Error 105 means the connection reached the bank, but the bank’s servers are slow, unresponsive, or actively blocking data retrieval often during maintenance or due to a bank-side block on third-party access. Error 103 is specifically an authentication rejection: the bank identified the login attempt but refused it. QuickBooks banking error 103 can also be fixed by updating credentials or completing a bank verification. Whereas for fixing
Error 105, you need to wait for the bank to restore normal service or refresh the bank connection.
| Error | What It Means | Primary Fix |
| QuickBooks Error 102 | Cannot connect to the bank at all. | Wait for bank maintenance to complete; retry. |
| QuickBooks Error 103 | Bank login credentials rejected. | Update username/password in QuickBooks; complete bank verification. |
| QuickBooks Error 105 | Connected but data cannot be retrieved. | Refresh connection; complete bank verification; wait for service restoration. |
| QuickBooks Error 106 | My bank account cannot be found. | Update account details; reconnect the account. |
| QuickBooks Error 108 | The bank has a message requiring action. | Log into the bank’s website and complete the required action. |

If Error 103 has returned after you updated your credentials, or if it has persisted for more than 24 hours, work through these escalation steps.
Confirm Your Bank Website Still Works
Sign in to your bank’s website and confirm you can access the account. If your login has changed since you last updated the connection in QuickBooks for example, your bank has forced a password reset or implemented new login requirements the credentials in QuickBooks are already outdated again. Update them immediately and run a manual sync.
Recheck Your Bank Credentials
Confirm you are using the latest username format that your bank requires. Some banks use an email address, others use an account number or a member ID, and others use a custom username. If the username format does not match what the bank expects, the credentials will always be rejected even when the password is correct. Check the bank’s login page for guidance on the required username format.
Try the Bank Connection Again Later
If your login details are correct and your bank’s website is working fine, but QuickBooks Error 103 still appears, wait for a few hours and try updating your bank account manually. Sometimes, temporary issues with the bank’s servers can interrupt the connection. These issues may resolve on their own once the bank’s systems start working normally again.
Check Whether Your Bank Changed Its Connection Requirements
Check your bank’s communications both email and in-portal messages for any announcements about changes to their online banking platform, updates to third-party access policies, or new security requirements. Banks occasionally introduce changes that break existing QuickBooks connections and require users to reconnect from scratch using the updated process.
Contact Your Bank if Online Banking Works but QuickBooks Cannot Connect
If you can log into your bank’s website successfully but QuickBooks continues to return Error 103, contact your bank’s business banking support team. Ask whether there are any restrictions on third-party data access for your account, whether any re-authorisation is required for connected services. Also, check whether there are known issues with QuickBooks connectivity. Some banks have account-level settings that block third-party data access and can only be enabled by the bank’s support team.
Contact QuickBooks Support if the Bank Connection Is Working Normally
If your bank confirms that everything is working fine at their end and no action is required, contact QuickBooks Online support. After this, provide them with your bank name, when the error first appeared, when the last successful sync occurred, and which troubleshooting method you have tried earlier.
Keep Your Bank Login Information Current
Update the credentials stored in the QuickBooks bank connection any time you change your online banking password or username.

Making this update immediately after any banking credential change prevents a gap in your transaction data.
Complete Bank Verification Requests Promptly

Banks block third-party data access for accounts with pending verifications, and a delayed response means your QuickBooks bank feed will stop working. Most banks send these requests by email or display them within the banking portal.
Monitor Changes to Your Bank’s Website/ Login Process
Follow the instructions by bank for notifications about platform updates/ changes to login process/ or new security requirements for connected services. When a bank introduces mandatory multi-factor authentication or migrates to a new platform, existing QuickBooks connections often need to be refreshed. Acting on these communications proactively avoids a bank feed interruption.
Keep QuickBooks Online Updated
QuickBooks Online updates automatically, but you need to maintain the browser you use to access it. Keep Chrome/ Edge/ or Firefox updated with the latest versions. Browser updates improve compatibility with QuickBooks Online’s interface and an outdated browser can cause errors.
Stay informed about changes to QuickBooks Online features and banking functionality by reviewing the latest QuickBooks Online updates.
Review Connected Bank Accounts Regularly
Check the Banking page in QuickBooks Online once a week to confirm that all connected accounts are syncing successfully and that the last updated date for each account is recent.
