Open Banking Explained

🔑 Your Bank Data, Shared on Your Terms

Open banking is a way for you to securely let other approved companies access your banking information, or make payments on your behalf, with your permission. Instead of a bank keeping all your data locked inside its own app, open banking lets you choose to share specific information with a budgeting app, a lender, or another service, through a secure connection. It is being rolled out in New Zealand to give people more control and choice over their own financial data.

                Key Point: Open banking lets you grant approved third parties secure, permission-based access to your bank data or the ability to initiate payments, without handing over your login details. You stay in control: you choose what to share, with whom, and you can withdraw permission. The secure connection means you never give your password to the third party, which is far safer than older methods of screen scraping.
            

The Two Main Things It Enables

Sharing account information: letting a service see your transactions or balances, for example a budgeting app.
Initiating payments: letting a service start a payment from your account with your approval, as an alternative to card payment.

🔗 How It Works Without Sharing Your Password

The crucial feature of open banking is that you never give the third party your banking password. Instead, the connection is made through a secure, official link between the third party and your bank, and you approve the access directly with your bank.

You choose a service and ask to connect your bank

You are sent to your bank to approve, logging in yourself

You consent to exactly what is shared, and for how long

The service receives only the agreed access, never your password

Why This Is Safer Than the Old Way

Before open banking, some apps asked for your actual banking username and password to log in on your behalf and copy your data, a practice called screen scraping. That meant handing your full credentials to a third party, which is risky and can breach your bank terms. Open banking replaces this with permission-based access where your password stays secret and you control the scope.

                Never hand over your login: A legitimate open banking connection sends you to your own bank to approve access; it never asks you to type your bank password into the third party app. If a service asks for your actual banking password, that is a red flag, not open banking.
            

⚖ Benefits and Risks

The Benefits

Benefit	What it means for you
Better tools	Budgeting and money apps can use real data to give useful insights
Easier switching and comparison	Services can assess your situation with your data, with consent
More payment choice	Pay directly from your account as an alternative to cards
More competition	New providers can offer services, which can lower costs

The Risks to Manage

Sharing with the wrong service: only connect to providers you trust and that are properly approved.
Over-sharing: grant only the access a service genuinely needs, for the time it needs it.
Forgotten connections: access you granted long ago may still be active if you do not review it.
Scams imitating open banking: fraudsters may try to mimic the flow to steal credentials.

                You can withdraw consent: A core principle of open banking is that you can review and revoke access. If you stop using a service, remove its access so it no longer connects to your data. Treat your data permissions like a list you tidy up regularly.
            

💡 Using Open Banking Wisely

Sensible Habits

Check the provider is legitimate and approved before connecting.
Read what you are consenting to: what data, what actions, and for how long.
Approve through your own bank, never by typing your bank password into another app.
Review your connections periodically and revoke any you no longer use.
Stay alert to scams that imitate the open banking flow.

What It Is Not

Open banking is not the bank selling your data behind your back; it is permission-based sharing that you control. It is also not a reason to lower your guard: the same scam awareness applies, because criminals will try to imitate any new system. Used carefully, it can make managing money easier and give you more choice, while keeping your password private.

                Control is the point: The whole idea of open banking is that your data works for you, on your terms. The value comes with the responsibility to choose trusted services, share only what is needed, and tidy up access you no longer use.
            

Pair this with our guide on bank account security to keep your accounts safe. Final word: open banking lets you securely share bank data or initiate payments with approved services, without giving away your password. It offers better tools, more choice, and more competition, as long as you connect only to trusted providers, share the minimum needed, and review your permissions. This is general information, not personalised financial advice.
