3D Secure 2.0: Protect Your Webshop From Fraud Without Losing Sales

Written by Cecilia | Oct 29, 2025, 11:00:00 AM

Running a successful webshop is all about finding the right balance between security and conversion. You need to protect your business against fraud and card misuse without creating so many obstacles that your customers abandon their purchase during the checkout flow.

The solution is 3D Secure 2.0 (3DS2). With a modern payment solution, security works intelligently in the background, allowing you to achieve maximum fraud protection, comply with legislation, and maintain a high conversion rate.

What is 3D Secure 2.0 (3DS2)?

3D Secure 2.0 (3DS2) is a global security standard for online payments that verifies the buyer's identity through data-sharing and authentication processes. The technology fulfills the EU's legal requirement for Strong Customer Authentication (SCA) and protects webshops against fraud by transferring the financial liability (liability shift) to the cardholder's issuing bank.

Unlike the older 3DS1 standard, 3DS2 evaluates the risk of a purchase in real time by analyzing over 100 data points (e.g., device data, historical behavior, and shipping address). This means the vast majority of transactions can be completed without requiring any extra action from the customer.

Why Are Cybersecurity and SCA Crucial for Your Webshop?

Cybersecurity on e-commerce sites is not just about preventing stolen goods; it is very much about protecting your revenue. A complicated and insecure checkout flow is one of the most common reasons online customers abandon their shopping carts.In the EU, the law mandates Strong Customer Authentication (SCA) for online payments. SCA requires the customer to confirm their identity using at least two of the following three factors:

Knowledge

Something the customer knows

E.g., a password or PIN code.

Possession

Something the customer has

E.g., a mobile phone or standard authenticator app.

Biometrics

Something the customer is

E.g., fingerprint or facial recognition.

With 3DS2, your webshop automatically fulfills all SCA requirements.

What is Liability Shift, and How Does It Protect Your Finances?

Liability shift is a financial rule that transfers the financial responsibility for fraudulent transactions and chargebacks from the webshop to the card-issuing bank once the transaction is validated via 3D Secure.

As a webshop owner, understanding the difference between payment solutions with and without integrated 3DS2 protection is essential. The table below illustrates the impact on your financial risk:

Comparison: With and Without 3DS2 Protection

Parameter	Scenario WITHOUT 3DS2 protection ❌	Scenario WITH pensopay & 3DS2 ✅
Transaction	Fraudster uses a stolen card.	Fraudulent transaction attempt is made.
Order handling	You ship the product in good faith.	The product is shipped after an approved risk assessment.
Customer dispute	Cardholder files a dispute (chargeback).	Cardholder files a dispute with their bank.
Financial consequence	The bank withdraws the funds from your account.	The card issuer's bank bears the loss.
Result for your webshop	You lose both the product and the money.	You keep your payment.

With pensopay, correct 3DS2 handling is built-in as standard, providing your business with maximum financial security.

How Does 3DS2 Work in Practice?

3D Secure 2.0 replaces old, cumbersome passwords with an intelligent risk assessment that runs invisibly in the background as soon as the customer clicks "Buy."

How the 3DS2 Flow Works

🛒 Customer clicks "Buy"

↓

🛡️ 3DS2 Risk Assessment in the background

Low risk (approx. 95%)

Frictionless Flow

Instant approval

Uncertain / High risk (approx. 5%)

Challenge Flow

Quick validation (e.g., MitID / 2FA)

↓

✅ Completed transaction

95% of purchases

The Frictionless Flow

The transaction is assessed as low risk. The purchase is approved instantly without additional steps for the customer. Conversion rates remain fully intact.

5% of purchases

The Challenge Flow

There is uncertainty regarding the transaction risk. The customer is prompted for quick two-factor authentication (e.g., in their banking app or via MitID).

This separation ensures you stop fraudsters while providing legitimate customers with a fast and smooth checkout experience.
