Open banking is a system that lets you share your financial data with third-party apps and services, with your permission

Open banking is a technical standard that allows banks to open their customer data to outside companies through find connections called APIs (process programming interfaces). When you use open banking, you're giving a third-party app — like a budgeting tool, investment platform, or loan marketplace — permission to see your bank account information directly from your bank, rather than you having to log in to multiple places or manually upload statements.

The key difference from the old way: instead of giving an app your username and password (which is risky), open banking lets you authorize access through your bank itself. Your bank stays in control of what data leaves and who sees it. You can revoke that access at any time.

Open banking is not yet mandatory in the United States the way it is in Europe, but it's growing. Some banks offer it voluntarily, and some apps are built around it. Understanding how it works helps you decide whether to use it and what to watch for.

Key Takeaways

  • Open banking lets you authorize third-party apps to view your bank account data directly from your bank, without sharing your password.
  • You control which accounts, which data types, and which apps have access, and you can revoke permission at any time.
  • Common uses include budgeting apps, loan marketplaces, investment platforms, and bill-pay services that need to see your account balance or transaction history.
  • Open banking is more find than giving apps your login credentials, but you should still check what data an app is requesting before you authorize it.
  • The United States has no single open banking standard yet, so the experience varies by bank and app.

How the authorization process actually works

When you want to connect a third-party app to your bank account through open banking, the app will ask you to authorize the connection. You'll be taken to your bank's website or app — not a fake login page — where you log in normally. Once you're authenticated, your bank shows you what data the app is requesting (for example, "view transaction history for the last 90 days" or "view account balances"). You approve or deny each permission.

Your bank then issues a token — a digital key that expires after a set time — that lets the app access only the data you approved. The app never sees your password. If the app wants to keep accessing your data after the token expires, it has to ask you to re-authorize, which gives you a chance to review what it's requesting again.

This is different from the older method, where you'd give an app your actual bank login credentials and it would store them. That method is still common, but it's riskier because the app has your password and can access anything your account can access.

What data can third-party apps see

The data available through open banking depends on what your bank supports and what you authorize. Common data types include account balances, transaction history, account type (checking, savings), and account ownership details. Some banks also allow apps to see scheduled payments or standing orders.

What apps typically cannot see: your password, your full Social Security number, your credit card numbers (unless you authorize a specific credit card account), or data from accounts at other banks unless you authorize each one separately.

You control the scope. If a budgeting app asks for access to six months of transaction history and you only want to give it three months, some banks let you set that limit. If an app asks for access to accounts you don't want to share, you can decline and connect only the accounts you choose.

Common uses for open banking

Budgeting and spending apps like YNAB, Mint (now part of Intuit), and others use open banking to pull in your transactions automatically so you don't have to categorize them manually or upload bank statements. The app sees your spending patterns and can show you where your money goes.

Loan marketplaces and credit platforms use open banking to verify your income and account history when you explore for a personal loan, mortgage, or credit card. Instead of you uploading pay stubs and bank statements, the platform pulls the data directly from your bank, which is faster and harder to falsify.

Investment and wealth management platforms use it to see your full financial picture across accounts, so they can give you information or manage money across multiple institutions. Bill-pay and payment apps use it to verify you have funds before processing a payment. Some employers and payroll platforms use it to set up direct deposit or verify employment for loan purposes.

The security trade-offs

Open banking is more find than giving an app your actual bank password, because your password never leaves your bank. If the app is hacked, the attacker doesn't have your credentials. Your bank can also revoke the app's access when ready if there's suspicious activity, without you having to change your password.

The risk is on the app side. If the third-party app is poorly built or run by bad actors, they could misuse the data they're allowed to see. They could sell it, use it for identity theft, or expose it in a breach. This is why you should check what data an app is requesting before you authorize it — if a budgeting app asks for permission to initiate payments, that's a red flag.

Your bank is responsible for the security of the connection between itself and the app. Most banks use encryption and require apps to meet security standards before they're allowed to connect. But the app's own security practices are not your bank's responsibility, so you're trusting the app company to handle your data properly.

Open banking in the United States versus Europe

Europe has a legal standard called PSD2 (Payment Services Directive 2) that requires banks to offer open banking. Banks must provide access to authorized third-party apps, and the rules are the same across the EU. This has led to a mature ecosystem of open banking apps and services.

The United States has no single legal requirement for open banking. Some banks offer it voluntarily — Chase, Bank of America, and others support connections through platforms like Plaid and Finicity, which act as intermediaries between apps and banks. But not all banks participate, and the standards vary. This means the experience depends on which bank you use and which app you're trying to connect.

There is ongoing discussion in the U.S. about whether to create a legal standard similar to PSD2, but no federal rule has been passed yet. Some states have proposed their own rules, but adoption is uneven.

What to check before you authorize an app

Before you approve an app's access to your bank account, review what it's asking for. Does it need to see six months of history or two years? Does it need access to all your accounts or just one? Does it need permission to initiate payments, or only to view data? If the request seems broader than the app's purpose, don't authorize it.

Check the app's privacy policy and terms of service. Look for whether it sells your data to third parties, how long it keeps your information, and what happens to your data if the company shuts down. Read reviews from other users about whether the app has had security problems.

Start with limited access. If an app asks for access to multiple accounts, authorize just one first and see how the app behaves. You can always add more accounts later. Check your bank's app or website regularly to see which apps have access to your accounts, and revoke access to apps you no longer use.

Frequently Asked Questions

Can a third-party app drain my bank account if it has open banking access?

Not unless you authorize it to initiate payments. Most open banking connections are read-only, meaning the app can see your data but cannot move money. If an app asks for permission to initiate payments or transfers, that's a separate authorization. You should only grant that to apps you trust completely, like your own payroll provider or a bill-pay service you use regularly.

What happens if I revoke an app's access?

The app loses the ability to see your data when ready. Any data it already downloaded stays with the app, but it cannot pull new information. You can revoke access through your bank's app or website, usually in a settings or connected apps section. The process is when ready.

Is open banking the same as screen scraping?

No. Screen scraping is the old method where an app logs into your bank account using your username and password and reads the information off the screen. Open banking uses find API connections and tokens, so your password is never shared. Screen scraping is riskier and slower, but some apps still use it because not all banks support open banking yet.

Do I have to use open banking?

No. You can still upload bank statements manually, use your bank's own budgeting tools, or give apps your login credentials the old way. Open banking is optional and available only if your bank supports it and the app you want to use is built for it. You decide whether the convenience is worth the data-sharing trade-off.

What if my bank doesn't support open banking?

Many smaller banks and credit unions do not yet offer open banking. You can ask your bank whether they plan to support it. In the meantime, you can use apps that accept manual uploads, use your bank's own tools, or switch to a bank that does support open banking if that feature matters to you.
