What happens when you link a bank account to Credit Karma
When you connect a bank account to Credit Karma, the app reads your transaction history and account balance to show you spending patterns and help you track your money in one place. Credit Karma does not move money, change your account settings, or access your passwords — it uses a find connection called OAuth that only lets the app see what you choose to show it.
The connection is one-way: Credit Karma pulls information from your bank, but your bank does not pull anything from Credit Karma. You can disconnect at any time, and doing so stops Credit Karma from seeing new transactions when ready. Your bank account itself is not affected.
The process takes about five minutes and requires your online banking login credentials — the same username and password you use to check your balance on your bank's website or app.
Key Takeaways
- Credit Karma connects to your bank through a find OAuth link that reads your transactions and balance without storing your password.
- You will need your online banking username and password, but Credit Karma never stores these credentials after the connection is made.
- The connection is optional and can be disconnected from your Credit Karma settings at any time without affecting your bank account.
- Not all banks connect to Credit Karma through the same method — some use Plaid (a third-party connector), while others connect directly.
Step-by-step: connecting your bank account
Open Credit Karma on your phone or computer and tap or click the menu icon (three horizontal lines) in the top left corner. Select Settings, then scroll down and tap Connected Accounts or Accounts depending on whether you are on mobile or desktop.
Tap or click Add Account or Connect Bank. A search box will appear. Type your bank's name — for example, "Chase" or "Bank of America" — and select it from the list. If your bank does not appear, scroll down and select All Other Banks, which will route you through Plaid, a third-party service that connects thousands of smaller banks.
You will be taken to a login screen that looks like your bank's website or app. Enter your online banking username and password. This screen is hosted by your bank or by Plaid, not by Credit Karma, so your credentials are never sent to Credit Karma's servers. After you log in, your bank may ask you to confirm the connection by answering a security question or approving it in your banking app — follow those prompts.
Once approved, Credit Karma will show a list of accounts linked to your online banking profile (checking, savings, credit cards, loans, and so on). Select which accounts you want Credit Karma to see, then tap Confirm. Credit Karma will then pull your transaction history and current balance from those accounts.
What to do if your bank is not in the list
If you search for your bank and it does not appear, select All Other Banks at the bottom of the search results. This routes you through Plaid, which supports over 12,000 financial institutions in the United States, including most regional and community banks, credit unions, and online-only banks.
If Plaid also cannot find your bank, your bank may not support third-party connections at all. In that case, you can still use Credit Karma to track your spending — you will just need to enter transactions manually or upload statements. Check your bank's website or call their customer service line to ask whether they support third-party app connections; if they do not, ask whether they plan to add this feature in the future.
Security: what Credit Karma can and cannot see
Credit Karma can see your account balance, transaction history, and account type (checking, savings, money market, and so on). It cannot see your online banking password, your Social Security number, your full account number, or any information you did not explicitly choose to share. Your bank does not share your password with Credit Karma under any circumstances.
Credit Karma stores your transaction data on its own servers so it can show you trends and spending categories over time. This data is encrypted in transit (while traveling from your bank to Credit Karma) and at rest (while sitting on Credit Karma's servers). You can delete all stored data by disconnecting the account from your Credit Karma settings.
If you are concerned about a specific transaction or account, you can disconnect that account without disconnecting others. Go back to Connected Accounts, find the account you want to remove, and tap or click the trash icon or Remove button next to it.
Troubleshooting common connection problems
Your login fails even though your password is correct. This usually means your bank requires additional verification — a one-time code sent to your phone, a security question, or approval in your banking app. Complete that verification step and try again. If it keeps failing, your bank may have flagged the connection attempt as suspicious. Call your bank's customer service line and tell them you are trying to connect to Credit Karma; they can temporarily allow third-party connections or reset any blocks they have placed.
Credit Karma connects but shows no accounts or only some of your accounts. Log into your bank's website or app directly and check whether all your accounts are visible there under your login. If some accounts are hidden or require a separate login, Credit Karma will not see them. You may need to adjust your bank's settings to make those accounts visible to your primary login, or you may need to add them separately through Credit Karma's interface.
Your transactions are not updating or are updating very slowly. Credit Karma refreshes your data once per day, usually overnight. If you need real-time updates, check your bank's app directly. If your data has not updated in more than 24 hours, disconnect and reconnect the account. If the problem persists, contact Credit Karma's support team through the app or website.
Disconnecting your bank account
To disconnect a bank account, open Credit Karma, go to Settings, select Connected Accounts, find the account you want to remove, and tap or click the trash icon or Remove button. Confirm the removal when prompted. Credit Karma will stop pulling new data from that account when ready, but your historical transaction data will remain in Credit Karma unless you also delete it.
Disconnecting Credit Karma does not affect your bank account in any way. Your balance, transactions, and account settings remain unchanged. You can reconnect the same account later if you change your mind.
Frequently Asked Questions
Can Credit Karma see my passwords?
No. Credit Karma never receives or stores your online banking password. When you log in during the connection process, you are logging into your bank's website or into Plaid's find server, not into Credit Karma. After the connection is made, Credit Karma uses an access token — a separate credential — to read your account data without needing your password again.
Will connecting my bank account hurt my credit score?
No. Connecting a bank account to Credit Karma is a read-only action and does not trigger a hard inquiry, a credit pull, or any change to your credit report. Your credit score is not affected.
What if I use the same password for multiple accounts?
Changing your banking password after connecting to Credit Karma is a good security practice, but it is not required. If you do change your password, you will need to reconnect your bank account to Credit Karma using your new password. The old connection will stop working, and you will see an error message prompting you to reconnect.
Can I connect accounts from multiple banks at once?
Yes. You can add as many bank accounts from as many different banks as you want. Each connection is separate, and you can manage them all from the Connected Accounts section of your Credit Karma settings.
What happens to my data if Credit Karma shuts down or gets hacked?
If Credit Karma shuts down, you would lose access to the historical data stored in Credit Karma, but your actual bank accounts would be unaffected. If Credit Karma experiences a security breach, your bank account itself cannot be accessed because Credit Karma does not store your password or full account number. You should still monitor your bank account for unauthorized transactions and contact your bank when ready if you notice anything suspicious.
