Cardholders may encounter 3D Secure as part of their purchase flow when shopping online. Merchants use 3D Secure as an authentication method to verify that the identity of the shopper matches the cardholder.
A growing number of online merchants use 3D Secure, and the Strong Customer Authentication regulation in Europe requires the use of 3D Secure for online purchases. The additional 3D Secure step at checkout typically involves showing the cardholder an authentication page on their bank’s website, where they are prompted to enter a verification code sent to their phone or email. This process is familiar to customers through the card networks’ brand names, such as Visa Secure and Mastercard Identity Check.
Example of a 3D Secure flow
When will 3D Secure be applied
When a customer buys something online and the merchant supports 3D Secure, the payment will be authenticated. The authorization attempt will come to Stripe for authentication where we will carry out a risk assessment. If the authorization is legitimate, the customer will be able to continue shopping unaffectetd, and if the authorization is risky, Stripe will authenticate the user on your behalf.
Depending on the options you enabled, Stripe will reach out to your cardholder via email or text to enter a one time passcode, or push them to their banking application on a mobile device to verify that they are making the purchase. At the time of authentication during the 3D Secure flow described above, you will have the option to customize the flow your cardholder goes through, see our integration guide for more information.
3D Secure shifts the liability for fraud disputes from the merchant to the issuer (you). It also requires Stripe to have complete up-to-date information on your cardholders to ensure we can reach out for authentication.
Payments that have been successfully authenticated using 3D Secure have a liability shift to the issuer applied to them. Should a 3D Secure payment be disputed as fraudulent by the cardholder, the liability shift will apply and you will automatically lose. Should a customer dispute a payment for any other reason (e.g., other), then the standard dispute process applies.
Liability shift will also occur if the issuer (you) are not enrolled in 3D Secure and the merchant is. The advantage of being enrolled in 3D Secure is that it will prevent successful authorizations when your cardholder was not present, and therefore prevent potential fraud from occuring.
