2fa could have come out due to the fact that:
- VBV/MCSC card
- The card’s Bin was blacklisted due to frequent payments using the same Bin
- The card you are using is not valid
- There is not enough balance on the card
- The anti-fraud system noticed a browser leak
- System settings do not match the cardholder
- Dirty or fraudulent IP address
How to bypass VBV:
- Use live Non-VBV/Non-MCSC cards
The 6-digit bin can be either VBV or Non-VBV. You need to select a 7-11 digit card number. More details in this topic:
"Bins without 3D Security, they are also nonVBV":
- Before paying, you need to warm up your account for 20-30 minutes or postpone the purchase until the next day
- When paying, leave the browser tabs for social networks and major news portals or other popular and trusted sites
- Create a clean digital fingerprint corresponding to the cardholder - IP address, time, time zone, operating system and keyboard language
