From 3D Secure payments 1.0 to 2.0: How important is this transition?

Over the past 70 years, we've witnessed a perpetual current of technological and regulatory shifts, from the advent of the magnetic strip in the 1960s to the implementation of PCI compliance in 2004, and the establishment of 3D Secure 1.0 in 1999.

Every technological development and regulatory adaptation has been instrumental in evolving the payments landscape into its current form. But the landscape has changed yet again. The support for 3D Secure 1.0.2 has ended, marking another critical turning point in the history of the payments industry.

The transition from 3D Secure 1.0 to 2.0 has now occurred, and it was far from being a mere version upgrade. This shift represented a comprehensive reimagining of 3D Secure payments, designed to more effectively cater to the complexities of today's digital marketplace.

In this article, we will explore the post-transition landscape of 3D Secure payments, looking at how this significant shift has influenced businesses, consumers, and the payments industry as a whole.

How 3D Secure works

As suggested in the name, Three Domain Security (3DS) is built around three domains:

1. The merchant domain, which supports the merchant plug-in (MPI). This has been renamed to 3DS Server in Version 2 protocol
2. The network or scheme domain, i.e. the card brand, which supports the directory server (DS)
3. The card issuer domain, which supports the access control server (ACS)

The merchant initiates the authentication request via the 3DS Server to the DS, which then forwards the request to the ACS for authentication.

The ACS can respond in three ways:

1. Authenticate [end of action]
2. Decline the authentication [end of action]
3. Request to challenge the cardholder

If the ACS has requested a challenge action:

• The 3DS Server needs to initiate a challenge request, providing details of how to surface the challenge to the cardholder
• The challenge is then presented to the customer as outlined in the request
• The customer completes the challenge in a 2-factor manner
• The ACS then decides to either:
• Authenticate [end of action]

Limitations of 3D Secure 1.0

While 3D Secure 1.0 played a significant role in shaping online transaction security, it had its limitations from a merchant's standpoint. Here's an insight into the challenges it posed:

1. Poor user experience leading to high abandonment rate: The 3D Secure 1.0 process can be disruptive to the online shopping experience. Customers are redirected to another page to verify their identity, which may confuse some users and lead to shopping cart abandonment. A study in 2022 revealed that 18% of online shoppers abandoned their cart because they “have no trust in the site”.
2. Lack of mobile-friendly design: 3D Secure 1.0 was designed before the rise of mobile commerce. Its user interface is often not optimized for mobile screens, leading to a subpar user experience for mobile shoppers.
3. Inefficient fraud detection: 3D Secure 1.0 applies the same level of security checks to all transactions, leading to unnecessary friction for low-risk transactions. This results in inefficiency and may contribute to higher abandonment rates.
4. Non-compliant with PSD2: The Payment Services Directive 2 (PSD2) regulation in the European Union requires Strong Customer Authentication (SCA), which 3D Secure 1.0 does not support, making it less suitable for businesses operating in the EU.
5. Less sophisticated risk-based authentication: 3D Secure 1.0 lacks the sophisticated risk-based authentication mechanism that 3D Secure 2.0 provides. This makes it less effective at balancing fraud prevention and user experience.

Leveling up from 1.0 to 2.0

On October 15, 2022, support for 3D Secure 1.0 was officially discontinued.

This sunsetting happened 21 months after the different card schemes announced their plan to support the original 3DS technology no longer. In the grand scheme of technological advancement, this milestone makes sense.

3D Secure 1.0 was built at a time when all we knew were bulky desktop devices. For our younger readers’ sake: Once upon a time, computers couldn’t fit in your backpack. Or your pocket. Or on your wrist. We’ve come a long way.

The 3DS protocol was a suboptimal user experience as consumers moved more of their shopping activities onto mobile devices. When 3D Secure 2.0 burst onto the scene in 2016, offering a slicker and less intrusive customer experience, we all knew V1’s end was near.

3D Secure 2.0 was designed to address the problems and shortcomings of 3D Secure 1.0, offering “frictionless authentication” and an improved customer experience. A key difference is the enforcement of SCA, which is essential if your business operates in Europe.

The new protocol, which was developed by EMVCo, supports all device options and covers a much wider range of use cases. 3DS 2.0:

• It uses ten times more assessment data points, leading to greater decision accuracy
• It allows for biometric authentication, reducing checkout time by 85%
• It doesn’t require redirects, decreasing cart abandonment by up to 70%

This is why moving forward, the card industry has defined 3DS 2.0 as the only supported customer authentication protocol.

The importance of the 3D Secure 2.0 transition for merchants

The transition to 3D Secure 2.0 represents a pivotal moment for merchants looking to ensure an optimized, secure, and seamless shopping experience for their customers. Here's why it's necessary.
