Adyen Authenticate Upgrade Uses Machine Learning to Drive 12% Payment Conversion Boost

Adyen has launched a significant upgrade to Authenticate, its real-time transaction routing engine within the Adyen Uplift suite. By automating the selection of authentication protocols and optimizing data shared with issuers, the platform aims to eliminate the friction that causes cart abandonment while reducing the compliance burden for merchants operating across fragmented international markets.

What was announced

The upgrade transforms Authenticate from a static rule-based system into a machine learning engine that makes three distinct decisions for every transaction: whether authentication is required, which method is most effective, and what specific data points will maximize the likelihood of issuer approval. Unlike traditional 3D Secure (3DS) providers, Adyen serves as both the acquirer and the authentication provider. This dual role allows its machine learning models, trained on trillions of historical interactions, to analyze the entire payment lifecycle down to the final authorization outcome rather than stopping at the authentication result alone.

The platform intelligently routes transactions between various protocols, including 3DS, Google Secure Payment Authentication (SPA), Mastercard Payment Passkeys, and Visa Payment Passkeys. By evaluating over 150 data fields, Authenticate can often perform "silent" authentication or remove the step entirely if a shopper is recognized through Adyen’s network-wide risk signals. Early pilot data indicates an 11% relative increase in payment conversion for users like Too Good To Go. Similarly, Just Eat Takeaway.com reported a 12% increase in conversion on eligible traffic.

Currently, Authenticate is live globally for 3DS and issuer optimization. In the UK, the platform is already processing live transactions using next-generation passkey technologies from Visa and Mastercard. The source release confirms that further enhancements and global expansion for these innovations are planned through 2027, aiming to keep pace with the rapid evolution of authentication technology without requiring additional development work from merchants.

"Authentication is evolving from a regulatory checkpoint into a trust layer for digital commerce. The future is not about choosing one protocol, but knowing when and how to use the right mechanism for each transaction. Authenticate is built to make that decision in context, helping turn authentication into a contributor to payment success rather than another step at checkout."

The companies involved

Adyen is a global financial technology platform that provides end-to-end payment capabilities, data-driven insights, and financial products in a single integrated solution. Headquartered in the Netherlands, the company has established itself as a primary competitor to legacy merchant acquirers and standalone payment gateways by owning the full payment stack. This infrastructure allows the firm to process payments across online, mobile, and in-store channels for a client base that includes major international retailers and digital marketplaces.

The effectiveness of Adyen’s network is bolstered by its scale; for a typical retail merchant on the platform, there is a greater than 90% probability that Adyen has previously processed a transaction for that specific shopper. This depth of data is what powers the company's fraud management module, Protect, and its optimization suite, Uplift. By combining real-time regulatory context with shopper signals, the company aims to eliminate the operational burden of global expansion for its users.

Among the early adopters of the Authenticate upgrade are Just Eat Takeaway.com, a leading global online food delivery marketplace where Sander Kole serves as Fintech Engineering Director, and Too Good To Go, a social impact company where Morten Keldebæk serves as CTO. These organizations represent the high-volume, cross-border digital commerce sector where authentication friction directly impacts bottom-line revenue.

What FF News has reported before

FF News has extensively tracked Adyen’s expansion and its shift toward AI-driven commerce solutions. In June 2026, the publication covered the launch of the Adyen Launches 'Agentic' Suite to Bridge the Gap Between Retailers and AI Commerce Platforms, which signaled the company's move toward bridging retail and AI. The firm’s focus on regional growth was highlighted in the Adyen Report: 40% of Hong Kong Retailers Target Global Expansion Amid Rising Fraud Risks, which detailed the specific security challenges facing merchants in Asia. Additionally, Adyen’s partnership strategy was evidenced by its work to Scale E-commerce Gifting Across Asia-Pacific with Limitless Technology and its collaboration with ROLLER and Adyen Launch Embedded Financing to support over 3,000 leisure venues.

What this means

This move signals a shift in the payments industry where authentication is no longer viewed as a "necessary evil" of compliance, but as a competitive lever for conversion. By integrating passkeys and Google SPA alongside 3DS, Adyen is putting pressure on legacy authentication providers that lack the acquiring data to make truly informed, real-time risk assessments. The challenge for the broader market remains the uneven adoption of these newer protocols by issuing banks. While the technology to bypass friction exists, its success depends on the willingness of issuers to trust third-party data signals over traditional, high-friction challenges. This development effectively raises the bar for what merchants expect from their payment partners.
