Adyen vs American Express

Adyen Upgrades Authenticate with AI Payment Optimization

Adyen has significantly expanded its authentication offering, Authenticate, as part of its Uplift optimization suite. The module now uses machine learning to route each transaction in real-time to the most appropriate authentication technology, replacing static 3DS rules. It integrates 3DS, Google Secure Payment Authentication, Mastercard and Visa Payment Passkeys, and pure data flows. The system dynamically decides whether authentication is needed, which method to use, and which data to send to card issuers, optimizing over 150 data fields for 3DS. It also works with Adyen's fraud management module Protect to recognize trusted buyers and minimize friction. Early customers report conversion gains: Too Good To Go saw an 11% relative increase in payment conversion, and Just Eat Takeaway.com reported a 12% higher conversion rate among qualifying visitors. Authenticate is now available worldwide for 3DS and issuer request optimization; newer methods like Google SPA and passkeys are being rolled out gradually, with live transactions already occurring in the UK and broader international rollout planned by 2027.
