Guavapay implements one of the most significant fraud prevention solutions - 3D Secure V2

3DS2 is a security protocol that provides an extra layer of protection for online credit and debit card purchases and it ensures the cardholder's authentication and protection against fraudulent transactions. 

3DS2 prompts compliance with SCA regulations that stipulate two-factor authentication as a requirement for all electronic payments which enables more effective prevention of fraud transactions.



More secure card payments with 2FA

Two-factor authentication (2FA), often called dual-factor authentication or two-step verification gives a more sophisticated level of protection by adding an extra layer of security to your online platforms. Instead of simply inputting your username and password, a two-factor authentication process requires additional information, such as a fingerprint,  security questions, SMS messages, OTPs, push notifications, and an answer to a code that’s been sent to you.
