What open banking is and why it matters to you
Open banking is a system that lets you give permission for one financial company to access your bank account information held at another company. Instead of logging into multiple websites or manually entering your account details, you authorize a third-party app or service to pull your data directly from your bank. Your bank then shares only the information you approved, nothing more.
The practical result: you can use a budgeting app to see all your accounts in one place, let a loan company check your income without mailing pay stubs, or give a tax preparation service direct access to your transaction history. Open banking is built on the idea that you own your data and should be able to move it around without handing over your password.
This matters because it changes how you handle refunds, tax information, and financial proof. Instead of waiting for a bank statement to arrive by mail or taking screenshots, you can give the organization handling your refund or payment direct, read-only access to verify your account details in real time.
Key Takeaways
- Open banking uses secure connections to let you share bank data with third-party apps without giving them your password.
- You control exactly what information is shared and can revoke access at any time through your bank's settings.
- The system relies on industry standards and encryption, but the bank you use determines how secure the connection is.
- Open banking is now used by tax services, refund tracking tools, and loan processors to verify your identity and account details faster.
- If something goes wrong, your bank is responsible for unauthorized access, not the third-party app.
How the connection between your bank and a third-party app actually works
When you authorize an app to access your bank account, you do not give it your username or password. Instead, your bank issues a temporary token—think of it as a special key that works only for that app and only for the data you approved. The app uses that token to request information directly from your bank's system.
The process usually looks like this: you open the budgeting app or refund tracker, click "connect your bank," and get sent to your actual bank's website. You log in there (not to the third-party app), review what data the app is asking for, and click approve. Your bank then generates the token and sends it back to the app. From that point on, the app can request your balance or transaction history, but it cannot change your password, move money, or access anything you did not approve.
The technical standard behind this is called OAuth 2.0 in most cases, or Open Banking APIs in regulated systems like Europe's PSD2. Both use the same principle: temporary, limited-scope access instead of full account credentials. Your bank holds the master key; the app holds only what you gave it permission to use.
What information can be shared and what stays private
When you connect an account through open banking, you see a permission screen that lists exactly what the app wants to see. Common requests include your account balance, transaction history for the past 90 days, account holder name, and routing and account numbers. Some apps ask for standing orders or scheduled payments. You approve or deny each category before the connection is made.
What cannot be shared: your password, your security questions, your credit card PIN, or any data you did not explicitly approve. If an app asks for your password during the connection process, that is not open banking—that is an older, less secure method called "screen scraping," and you should stop and use a different service.
For refund and tax purposes, this means a tax service can see your W-2 income and bank deposits without you uploading documents, and a refund tracker can confirm your account details match what you reported. The service sees only what it needs to do its job, and you can see exactly what it is accessing in your bank's app under connected services or authorized apps.
How to connect your bank account safely through open banking
Start by opening the app or service that needs your bank information. Look for a button that says "connect your bank," "link your account," or "add your bank." Click it and you will be taken to your actual bank's login page—not a copy, but your real bank's website. This is the security checkpoint: if the page does not look like your bank's normal login, stop and close the browser.
Log in with your regular credentials. You will then see a permission screen listing what the app wants to access. Read it carefully. If the app is asking for permission to move money or change settings, that is a red flag—refund trackers and tax services do not need that. Approve only what makes sense for what the app does.
After you approve, you will be sent back to the app, and the connection is live. Go to your bank's app or website and look for a section called "connected apps," "authorized services," or "app permissions." You should see the app listed there. If it is not, the connection did not work and you should try again or contact the app's support.
Revoking access and what happens when you disconnect
You can stop an app from accessing your bank data at any time, and you do not need the app's permission to do it. Open your bank's app or website, find the connected apps section, and click "disconnect" or "revoke access" next to the app's name. The connection ends immediately. The app will no longer be able to see your account information, though it may still have a record of data it already downloaded before you disconnected.
When you disconnect, the app usually stops working—it will ask you to reconnect if you want to use it again. Some apps let you keep using cached data (information they already downloaded), but they cannot pull fresh updates. If you reconnected later, the app would get a new token and start over.
Disconnecting does not delete your account with the app or erase your history there. It only cuts off the live connection to your bank. If you want to fully remove your data from the app, you usually need to delete your account within the app itself, which is a separate step.
What to do if you think something went wrong with your connection
If an app is showing outdated information, the connection may have expired or been interrupted. Try disconnecting and reconnecting. Go to your bank's app, revoke access to the app, then go back to the app and click "connect your bank" again. You will log in to your bank once more, approve the permissions, and get a fresh token. This usually fixes sync problems.
If you see an app listed in your bank's connected apps section that you do not recognize, revoke it immediately. Then change your bank password as a precaution. Open banking tokens cannot be used to log in to your account, but if someone else authorized an app on your account, they may have had access to your login at some point.
If an app is showing an error when you try to connect, check your bank's status page to see if there is a known outage. Some banks temporarily disable open banking connections during maintenance. If there is no outage, try a different browser or clear your browser's cache and cookies, then try again. If the problem persists, contact the app's support team—they can see on their end whether the connection request reached your bank.
How open banking affects refund tracking and tax filing
Tax preparation services increasingly use open banking to pull your income information directly from your bank instead of asking you to upload W-2s or pay stubs. When you connect your bank account, the service can see deposits from your employer and verify your income matches what you reported. This speeds up verification and reduces the back-and-forth of uploading documents.
Refund tracking tools use open banking to confirm your bank account details are correct before you submit a refund claim. Instead of typing your routing and account number and hoping you got it right, the tool can verify it matches what your bank has on file. This reduces the risk of a refund being sent to the wrong account.
For government refunds like tax refunds or stimulus payments, open banking does not change how the government sends the money—it still goes through the ACH system and takes the same number of days. But it can speed up the verification step that happens before the payment is issued. Some state tax agencies now offer open banking as an option to verify your identity without mailing documents.
Frequently Asked Questions
Is open banking safe? Can the app steal my money?
Open banking is safer than giving an app your password because the app never sees your credentials. The token it receives is read-only and limited to the data you approved. Your bank is responsible for the security of the token and the connection. If someone uses an app to fraudulently access your account, your bank's fraud protection covers you, not the app.
What if I disconnect an app and it keeps trying to access my account?
Once you revoke access in your bank's app, the token expires and the app cannot make new requests. If an app is still showing your data after you disconnected, it is using cached information it downloaded before you revoked access, not live data from your bank. The app cannot pull fresh updates. If you want to ensure it has no data at all, delete your account within the app itself.
Do I have to use open banking, or can I still upload documents?
Most services that offer open banking also let you upload documents or enter information manually. Open banking is optional and usually faster, but you can choose the method that works for you. If a service requires open banking and you are not comfortable with it, you can use a different service instead.
Can my employer or the government see that I connected an app to my bank?
No. The connection is between you, your bank, and the app. Your employer and the government cannot see which apps you have authorized. They can only see the information you choose to share with them—like your income or account details you provide on a form.
What happens to my data if the app shuts down?
When an app shuts down, your access token becomes useless and the app can no longer pull new data from your bank. Any data the app already downloaded may still be stored on the company's servers, depending on their data retention policy. You should revoke access before the shutdown if possible. Check the app's privacy policy to see how long they keep data after you delete your account.
