With the correct geo-configuration for the cardholder and the use of valid cards with NON-VBV BINs, you can successfully pay for any website, including 3D-Secure, as the payment gateway will not request an OTP.
Newcomers can try 2D-Secure websites with weak anti-fraud protection (or none at all, and the payment is successfully processed by the payment gateway).
A list of such websites can be found in these threads:
Beginners, Don’t waste your time on G2A. These sites are 2d secure:
offgamers .com
thecardcloset.com
cdkeys.com
raise.com
giftcardgranny.com/buy-gift-cards/
cardpool.com
Even if a website/online store has switched from 2D-Secure to 3D-Secure technology, any valid card with NON-VBV BINs will still be successfully authorized.
