The most common reason Plaid fails is a mismatch between your login credentials and what the bank has on file
Plaid connects to your bank by asking you to enter your online banking username and password. If that password has changed since you last logged in directly, or if your bank locked your account after too many failed login attempts, Plaid will be rejected. The same happens if your bank requires a second authentication step—like a code from an app or a text message—that Plaid cannot complete on its own.
Before you troubleshoot anything else, log into your bank's website or app directly using the same credentials you are about to give Plaid. If you cannot log in there, you will not be able to log in through Plaid. If you can log in directly but Plaid still fails, the problem is usually one of the specific issues listed below.
Key Takeaways
- Test your bank login directly on your bank's website first—if you cannot log in there, Plaid cannot either.
- Banks that require two-factor authentication (a code sent to your phone or generated by an app) often block Plaid connections unless you disable that requirement temporarily or use a backup login method.
- Some banks do not work with Plaid at all, or only work with certain versions of Plaid that specific apps use.
- Your bank may have flagged your account for suspicious activity and locked it, which blocks all login attempts including Plaid's.
- Clearing your browser cache and cookies, then trying again in an incognito window, resolves many connection failures that are not caused by your bank.
Your bank requires two-factor authentication that Plaid cannot handle
Many banks now require a second step after you enter your password—a code texted to your phone, a push notification to an app, or a number from an authenticator app. Plaid cannot complete these steps automatically. When your bank asks for the code, Plaid stops and the connection fails.
The fix depends on your bank. Some banks let you create a separate "app password" or "device password" that bypasses two-factor authentication. Others let you mark a device as trusted so that future logins from that device do not require the second step. A few banks have a specific setting to allow third-party apps like Plaid to connect without the second factor. Log into your bank's security or settings page and look for language like "app passwords", "trusted devices", "third-party access", or "connected apps". If you cannot find it, call your bank's support line and ask whether they allow Plaid connections and what setup is required.
Your bank account is locked or flagged
If your bank suspects unusual activity—too many failed login attempts, a login from an unfamiliar location, or a sudden spike in account access—it may lock your account temporarily or require you to verify your identity before allowing any login, including Plaid's.
Check your email for messages from your bank about account security or suspicious activity. If you see one, follow the link in that email to unlock your account or verify your identity. Do not click links in unsolicited emails claiming to be from your bank; instead, go directly to your bank's website by typing the address yourself. Once your account is unlocked, try Plaid again. If you do not see an email but suspect your account is locked, call your bank directly to confirm.
Your bank does not work with Plaid, or only works with certain apps
Plaid connects to thousands of banks and credit unions, but not all of them. Some smaller regional banks, credit unions, and international banks do not have Plaid integration. A few large banks have restrictions—they may work with Plaid only for certain types of apps (like investment apps but not budgeting apps) or only through specific versions of Plaid that certain financial companies use.
Before you spend time troubleshooting, check whether your bank is on Plaid's list of supported institutions. Go to plaid.com/institutions and search for your bank by name. If it does not appear, or if it appears with a note about limited support, Plaid cannot connect to that bank. In that case, the app you are trying to use may offer an alternative connection method—manual upload of statements, direct entry of account numbers, or a different aggregator service. Contact the app's support team to ask what options are available for your bank.
You are using the wrong login method or credentials
Some banks have multiple login options—a username and password, a card number and PIN, a phone number and passcode, or a mobile app login. Plaid usually requires the username and password method, not the card-based or phone-based login. If you normally log into your bank using your debit card number and PIN, or if you only use the mobile app and have never set up a username, Plaid will fail.
Check your bank's website to see whether you have a username-and-password login set up. If you do not, you may need to create one before Plaid can connect. If you do have one but have not used it in a long time, your bank may have deactivated it. Call your bank or log into their website directly to confirm your username and password are active and correct.
Browser cache, cookies, or a temporary glitch is blocking the connection
Plaid works through your web browser when you connect it from a computer. If your browser's cache or cookies are corrupted, or if Plaid's servers are experiencing a temporary outage, the connection will fail even though your bank login is correct.
Clear your browser's cache and cookies, then try again in an incognito or private window. This removes any stored data that might be interfering with the connection. If you are on a phone or tablet, try the connection in a different browser or in the app itself rather than through a web browser. If the problem persists across multiple browsers and devices, wait a few hours and try again—Plaid or your bank may be experiencing a temporary outage.
Your bank changed its login system or security requirements
Banks periodically update their login systems, security protocols, or the way they communicate with third-party services like Plaid. When a bank makes a major change, Plaid may need time to update its connection on its end. During that window, connections fail even though nothing is wrong with your account.
If your bank recently sent you a notice about a security update, a new login system, or a change to how they handle third-party access, that may be the cause. Check your bank's website or call their support line to ask whether they recently made changes that affect third-party apps. If they did, ask whether Plaid is compatible with the new system and whether there is a timeline for full compatibility. You may need to wait a few days or weeks for Plaid to catch up.
Frequently Asked Questions
Is it safe to give Plaid my bank password?
Plaid is a legitimate service used by thousands of financial apps and banks. It does not store your password—it uses it only to log in on your behalf, then discards it. However, you are giving a third party access to your account. If you are uncomfortable with that, you can ask your bank whether they offer a direct connection to the app you are trying to use, or whether they support app passwords or trusted device settings that would let you connect without sharing your main password.
Will Plaid work if I change my password after connecting?
No. If you change your bank password after Plaid connects, Plaid will use the old password the next time it tries to access your account and will fail. You will need to disconnect Plaid from the app you are using, then reconnect it with your new password. Most apps have a "reconnect" or "update connection" button in their settings.
What should I do if Plaid says my bank is not supported?
Plaid's list of supported banks is not complete for every institution. If Plaid says your bank is not supported, contact the app you are trying to use and ask what alternative connection methods they offer. Many apps allow you to manually upload bank statements, enter account information by hand, or use a different service to connect your bank.
Can I use Plaid if my bank requires a PIN instead of a password?
Most banks that use PIN-based login do not work with Plaid. You will need to set up a username-and-password login through your bank's website first. If your bank does not offer that option, contact their support team to ask whether they have an alternative method for third-party app connections.
How long does it usually take Plaid to connect?
A successful Plaid connection usually completes in seconds to a few minutes. If it is taking longer than five minutes, something has gone wrong—either your credentials are incorrect, your bank is blocking the connection, or there is a temporary outage. Stop and try again after clearing your browser cache, or wait a few hours before attempting again.
