The most common reason: your bank blocks third-party connections
Fidelity uses a service called Plaid to connect to your bank account. Plaid acts as the middleman—it reads your login credentials and pulls your account information into Fidelity so you can see balances, transfer money, or set up automatic deposits. But Plaid can only work if your bank allows it. Many banks, especially regional and community banks, do not permit third-party apps to connect this way, even though you own the account.
When you try to link your account and see an error message, the first thing to check is whether your specific bank is on Plaid's supported list. You can search your bank's name on Plaid's website to confirm. If your bank is not listed, or if it is listed but your particular branch or account type is not supported, the connection will fail no matter what you do on Fidelity's end.
Some banks support Plaid for checking accounts but not savings accounts, or for personal accounts but not business accounts. The limitation is set by the bank, not by Fidelity or Plaid.
Key Takeaways
- Your bank may not allow Plaid to connect to it, even if Fidelity supports the connection—check Plaid's supported banks list to confirm your bank is included.
- If your bank blocks third-party connections, you can still fund your Fidelity account by transferring money directly from your bank's website or app.
- Some banks require you to whitelist Plaid or approve the connection in your bank's security settings before the link will work.
- If your bank is supported but the connection still fails, the problem is usually an incorrect password, a locked account, or a security block triggered by the login attempt.
- Fidelity's customer service can see the exact error your bank returned and can tell you whether the issue is on your bank's side or something you can fix.
Your bank requires you to approve the connection first
Some banks, particularly larger ones, support Plaid but require you to take an extra step before the connection works. Your bank may send you an email asking you to confirm that you authorized Fidelity to access your account, or it may require you to log into your bank's security settings and whitelist Plaid as a trusted app.
If you see a message saying the connection failed or timed out, check your email—including spam and promotions folders—for a message from your bank asking you to confirm. If you find one, click the link and approve the request. Then go back to Fidelity and try linking again.
Some banks also flag the connection attempt as suspicious because it is coming from an unfamiliar device or location. If you recently moved, changed your phone, or are logging in from a different country, your bank may have blocked the Plaid connection automatically. Log into your bank's app or website directly, confirm your identity if prompted, and then try the Fidelity link again.
You entered your password incorrectly, or your account is locked
When you link your bank account to Fidelity through Plaid, you enter your bank login credentials directly into Plaid's interface—not into Fidelity. If you mistype your password or username, the connection will fail when ready. The error message usually says something like "invalid credentials" or "login failed."
If you have tried multiple times with different passwords, your bank may have locked your account temporarily as a security measure. This is especially common if you entered the wrong password three or more times in a row. You will need to unlock your account through your bank's website or by calling your bank's customer service line before you can try linking again.
If you are not sure whether your password is correct, log into your bank's website or app directly first. Once you confirm you can access your account that way, try the Fidelity link again using the same password.
Your bank uses a different authentication method that Plaid does not support
Some banks, particularly credit unions and smaller institutions, use security methods that Plaid cannot read. For example, if your bank requires you to answer security questions, use a hardware token, or scan a QR code every time you log in, Plaid will not be able to complete the connection because it cannot respond to those prompts.
A few banks also use single sign-on systems—where you log in through a third party like Google or your employer's network—instead of a traditional username and password. Plaid cannot work with these systems either.
If your bank uses one of these methods, you cannot link through Plaid. The alternative is to transfer money to Fidelity manually: log into your bank's website or app, initiate an outgoing transfer, and enter Fidelity's routing and account numbers. This takes one to three business days but works with any bank.
Fidelity's servers or Plaid's service is temporarily down
Plaid and Fidelity both perform maintenance and updates, usually at night or on weekends. If you try to link your account during maintenance, you will see a timeout error or a message saying the service is unavailable. This is temporary and not something you caused.
Wait 30 minutes to an hour and try again. If the problem persists, check Fidelity's status page or Plaid's status page to see if there is a known outage. Both companies post updates there when their systems are down.
Your account type or account status is not supported
Fidelity can link to most personal checking and savings accounts, but some account types fall outside that scope. Joint accounts, trust accounts, accounts held in a business name, and accounts at banks outside the United States may not be linkable through Plaid, even if the bank itself is supported.
If you have a joint account, try linking using only your name and credentials. If the account is in a trust or business name, you may need to contact Fidelity to discuss alternative funding methods.
Accounts that are frozen, closed, or flagged for suspicious activity also will not link. If your account has any of these statuses, you will need to resolve the issue with your bank first.
What to do when the link fails
Start by confirming your password is correct by logging into your bank directly. Then check whether your bank is on Plaid's supported list. If it is not, skip the linking step and transfer money manually instead.
If your bank is supported, wait a few minutes and try the link again—sometimes the connection times out for no reason and works on the second attempt. If it fails again, contact Fidelity's customer service and tell them the exact error message you saw. Fidelity can see which bank returned the error and what it said, which narrows down whether the problem is on your bank's side, Plaid's side, or something you can fix yourself.
In the meantime, you can fund your Fidelity account by transferring money directly from your bank. Log into your bank's website or app, select "send money" or "transfer," and enter Fidelity's routing number and your Fidelity account number. The transfer will arrive in one to three business days. This method works with any bank, regardless of whether it supports Plaid.
Frequently Asked Questions
Can I link my account if my bank is not on Plaid's list?
No, not through Plaid. But you can still move money to Fidelity by initiating a transfer from your bank's website or app. This takes longer—usually one to three business days—but it works with any bank.
What if I see a message saying my bank does not support this feature?
That message means your bank has chosen not to allow third-party apps like Plaid to connect to it. You will need to transfer money manually from your bank instead. Contact your bank if you want to request that they add Plaid support.
Do I have to give Fidelity my bank password?
You enter your password into Plaid's interface, not directly into Fidelity. Plaid is a separate company that handles the connection securely. Fidelity never sees your actual password. If you are uncomfortable with this, use manual transfers instead.
How long does it take to link my account?
If the connection succeeds, it is usually when ready. If it fails, troubleshooting can take anywhere from a few minutes (if it is just a typo) to a few hours (if your bank needs to approve the connection). Manual transfers take one to three business days.
Will linking my account hurt my credit score?
No. Plaid reads your account information but does not perform a hard credit inquiry. Your credit score is not affected.
