3d secure is a function to improve the security for credit cards for online usage (additional password). U have to contact your credit card issuer / your bank to unlock it and register properly.

Most cryptocurrency exchanges that offer credit card purchases will employ 3-D Secure as an additional security measure against fraud. They have to be super careful about fraudulent purchases because Bitcoin payments are irreversible. Most other online merchants don't need to be quite so careful.

Can you use bank wire or SEPA transfer to fund an exchange account? Or do you only have credit cards?

Do any of your credit cards use the "MasterCard SecureCode" or "Verified by Visa" brands? Those use the 3-D Secure protocol.

The reason is most likely because merchants who accept credit cards for bitcoin is more likely to be victims of fraud than simple purchases of goods, because of the fact that bitcoin is irreversible as well as being extremely liquid which makes it perfect for a lot of the credit card scammers out there.

That's the primary reason that these exchanges ask for this 3D secure thing.

I honestly don't know what you can do in this case, other than contacting your bank and asking for a replacement card with this 3D secure thing, or even switching banks for that matter. However, you could try potentially linking the credit card to your paypal account, and purchasing BTC using Paypal on Virwox or other exchanges that way.
