3D Secure Authentication
3D Secure authentication, also called payer authentication, is a security procedure for online credit and debit card transactions. Launched by Visa in 2001 as Verified by Visa, it asks the cardholder for an extra password or one-time PIN before a purchase completes, which reduces online fraud and chargebacks and shifts liability for unauthorized transactions from the merchant to the issuing bank.
Scope: For online merchants and shoppers who want to understand what 3D Secure is, how the authentication flow works, and the fraud and chargeback protection it provides.
What Is 3D Secure Authentication?
In 2001, Visa launched 3D Secure (then called Verified by Visa), a measure for preventing fraud. 3D Secure Authentication, often known as payer authentication, is a security procedure for online credit and debit card transactions that helps to avoid fraud. It enables banks to verify a purchase by requesting extra information from the cardholder.
When you make an online card transaction, you can enable 3D Secure as an extra step. It improves both shopper and vendor security. Enabling 3D Secure asks for a PIN code every time you make a purchase. 3D Secure is also known as 3 Domain Secure; the three domains are the customer, the merchant, and the 3DS infrastructure platforms respectively.
How 3D Secure Works
To ensure you are the card owner, 3DS determines whether extra safekeeping is necessary when you make an online transaction. Upon doing so, it directs you to a 3DS page, where you'll have to enter a password or PIN if required. Your bank produces a one-time PIN and delivers it to your phone through SMS at the same time. Before completing the transaction, you enter this PIN.
• Payment is initiated.
• The shopper is directed to the 3D Secure authentication page.
• The system checks for the password registered in advance.
• Password matches: the payment is successful.
• Password wrong: an authentication error message appears.
Benefits of 3D Secure
• 3 Domain Secure adds an extra layer of protection for both you and your clients, preventing card information from being stolen and used online. It also guards against chargebacks for transactions that were not authorized. 3 Domain Secure transfers the liability from the merchant to the issuing bank, which means you'll save time and money by having fewer customer settlement issues.
• 3D Secure helps to lower online fraud, such as identity theft and illegal card use. It safeguards cardholder data and boosts client trust in your website.
• You may check whether a buyer is a legitimate cardholder using 3D Secure. If a fraudster tries to make a purchase in your online store, 3 Domain Secure will stop them, and you won't have to worry about chargebacks or disputes.
• The fear caused by scamming makes people hesitant towards online shopping. Customers are more eager to purchase through a site that employs 3D Secure, according to Verified by Visa, which says that their product promotes online shopping.

When an online payment is made, the shopper is directed to a 3D Secure page and asked for a password or PIN. The bank generates a one-time PIN and sends it to the cardholder's phone by SMS. If the code matches, the payment completes; if not, an authentication error appears.
Does 3D Secure protect merchants from chargebacks?
Yes. 3D Secure guards against chargebacks for transactions that were not authorized by shifting liability from the merchant to the issuing bank. Because the buyer is verified as the legitimate cardholder, merchants face fewer disputes and settlement issues.
Why do the three domains in 3D Secure matter?
3D Secure stands for 3 Domain Secure, referring to the customer, the merchant, and the 3DS infrastructure platforms. Involving all three parties in authentication ensures the person making the purchase is the real cardholder, which lowers identity theft and illegal card use.
