In this season of #TheShot, we focus on authentication: the step that confirms a cardholder is who they claim to be, before the issuer decides whether to authorize the payment. It shapes fraud rates, conversion and the customer experience, and in Europe it is also a regulatory obligation.
Our guest is Sandra Mianda, Founder & CEO of Paypr.work, back after Season 1 on BINs. Across six episodes, she follows authentication from the arrival of 3D-Secure to PSD2 and Strong Customer Authentication, regional differences in enforcement, and the question of trust behind delegated and demoted authentication.
Authentication sits between the checkout and the authorization, and PSPs, PayFacs, ISOs and ISVs run it on behalf of all their merchants. Deciding when to trigger 3DS, how to handle delegated flows and how to adapt rules market by market directly shapes the approval rates, fraud liability and checkout experience their merchants get.
