Common reasons your bank account won't link to Fidelity
Fidelity uses a third-party service called Plaid to connect your bank account, and the connection fails most often because of a mismatch between what you entered and what your bank has on file. The most common culprits are an incorrect password, a username that differs from your login credentials, or security settings that block third-party access even after you've typed everything correctly.
Your bank may also require you to turn on a specific permission before Plaid can see your account. Some banks—particularly smaller regional banks and credit unions—don't work with Plaid at all, which means Fidelity cannot connect to them through the automated route. In those cases, you'll need to use manual transfer methods instead.
If you've recently changed your bank password, changed your login method (such as switching to biometric login), or enabled multi-factor authentication, Plaid won't recognize your old credentials and the link will fail. The error message you see often doesn't pinpoint the real problem, so you may need to troubleshoot several possibilities before the connection works.
Key Takeaways
- Fidelity uses Plaid to connect bank accounts, and the connection fails most often because your password, username, or security settings don't match what Plaid expects.
- If your bank doesn't work with Plaid, you cannot use the automated linking method and must transfer money manually instead.
- Changing your bank password, enabling multi-factor authentication, or switching to biometric login will break an existing Plaid connection and require you to re-enter your credentials.
- Some banks require you to turn on third-party access permissions before Plaid can connect, even if you've entered your login details correctly.
How to check if your bank works with Plaid
Before you spend time troubleshooting, confirm that your bank is on Plaid's supported list. Go to Plaid's website (plaid.com) and use their search tool to type in your bank's name. If your bank appears in the results, it supports Plaid connections. If it doesn't appear, Fidelity cannot connect to it through the automated method.
If your bank isn't supported by Plaid, you have two options: transfer money manually from your bank to Fidelity using your bank's website or app, or contact Fidelity to see if they offer a direct transfer method for your specific bank. Some banks have direct relationships with Fidelity that bypass Plaid entirely, though these are less common.
Password and login credential problems
Plaid needs your actual bank login credentials—the same username and password you use to log into your bank's website or app. Many people enter a variation of their password or username and don't realize it's different from what the bank has on file. If you're unsure of your exact credentials, log into your bank directly first to confirm they work, then use those same credentials in Fidelity.
If you've changed your bank password recently, your old password won't work in Plaid. You must update your credentials in Fidelity by unlinking the account and linking it again with your new password. The same applies if you've changed your username or switched to a different login method—Plaid stores the credentials you gave it, and if those credentials no longer work at your bank, the connection will fail.
Some banks use a PIN or security code instead of a password for online access. If your bank does this, enter the PIN in the password field when Plaid asks for it. If you're not sure what your bank requires, call your bank's customer service line and ask what credentials you need to log in online.
Multi-factor authentication and security blocks
If your bank requires multi-factor authentication—such as a code sent to your phone or email—Plaid cannot complete the connection on its own. You'll see an error message, and the link will fail. To fix this, you need to turn off multi-factor authentication temporarily, complete the Plaid connection, then turn it back on. Once Plaid has linked your account, it stores a secure token and won't need to re-enter your credentials every time.
Some banks also have security settings that block third-party apps from accessing your account, even if you've entered your credentials correctly. Log into your bank's website or app and look for settings labeled "third-party access," "app permissions," or "connected apps." Enable access for Plaid or any third-party service, then try linking again in Fidelity.
If you're not sure whether your bank has these settings, call your bank's customer service line and ask if they require you to turn on third-party access before Plaid can connect. Some banks have this turned off by default for security reasons.
When Plaid shows an error message
Plaid displays different error messages depending on what went wrong. An "invalid credentials" message means your username or password is incorrect—go back and re-enter them carefully, or log into your bank directly to confirm they're right. A "connection timeout" message usually means Plaid couldn't reach your bank's servers, which is often temporary; wait a few minutes and try again.
If you see a message about multi-factor authentication or security verification, your bank is asking for additional confirmation before Plaid can access your account. You may need to log into your bank separately and approve the connection, or turn off multi-factor authentication as described above. Some banks send you a code via text or email that you need to enter in Plaid to complete the connection.
If the error message persists after you've tried these steps, take a screenshot of the exact error and contact Fidelity's customer service. They can see which step in the Plaid process is failing and may be able to work with your bank to resolve it. Fidelity also offers phone support, which is faster than email for troubleshooting connection problems.
Manual transfer methods if linking doesn't work
If your bank doesn't support Plaid or the connection keeps failing after you've tried the steps above, you can transfer money to Fidelity manually. Log into your bank's website or app and set up an external transfer to your Fidelity account. You'll need your Fidelity account number and routing number, which you can find in Fidelity's account settings or by calling Fidelity customer service.
Manual transfers usually take one to three business days to appear in your Fidelity account, depending on your bank and the time of day you initiate the transfer. This method is slower than linking, but it works with any bank and doesn't require Plaid to function. Once the transfer arrives, you can invest the money or hold it in your cash account.
Some banks also allow you to set up recurring transfers, so you can automate deposits to Fidelity without linking the account. This is a good option if you plan to transfer money regularly and want to avoid the hassle of manual transfers each time.
Unlinking and relinking your account
If your connection has worked before but stopped working, or if you've changed your bank password or security settings, you may need to unlink and relink your account. In Fidelity, go to your account settings, find the linked bank account, and select the option to unlink or disconnect it. Then follow the linking process again from the beginning, entering your current bank credentials.
Unlinking does not affect your Fidelity account or any money you've already transferred. It only removes the automated connection between Fidelity and your bank. After you relink, the connection should work with your updated credentials or new security settings.
If relinking still doesn't work, wait 24 hours before trying again. Sometimes Plaid's servers need time to refresh after an unlink, and attempting to relink too quickly can cause the connection to fail again.
Frequently Asked Questions
Can I link my credit card to Fidelity instead of my bank account?
No. Fidelity only links to bank accounts, not credit cards. You can transfer money from your bank account to Fidelity, but you cannot link a credit card directly. If you want to fund your Fidelity account with a credit card, you would need to transfer the money to your bank account first, then transfer it to Fidelity.
Why does Fidelity keep asking me to re-enter my bank password?
If Fidelity asks for your password every time you log in, the Plaid connection may not have saved your credentials properly. Try unlinking and relinking your account. If the problem continues, contact Fidelity to confirm the connection was successful. Some banks also require re-authentication if you haven't accessed your account in a certain period of time.
What if my bank is very small or a credit union?
Small banks and credit unions are less likely to be supported by Plaid. Check Plaid's website first to see if your bank is listed. If it's not, you'll need to use manual transfers. Contact your bank or Fidelity to ask if they have a direct transfer relationship that doesn't require Plaid.
How long does it take for a linked bank account to work?
Once the connection is successful, transfers usually appear in your Fidelity account within one to three business days, depending on your bank. The linking process itself is instant—if Plaid accepts your credentials, the connection is active right away.
Can I link multiple bank accounts to Fidelity?
Yes. You can link as many bank accounts as you want to a single Fidelity account. Each one goes through the same Plaid process, and you can manage them all in your Fidelity settings.
