Authenticating order on GreenManGaming

is the 2nd one a password thinggy about your credit card?

I need to reenter my card details once more - here is what it says.

Protect Your Card From Unauthorised Use Online
Santander Secure, provided in association with Verified by Visa, protects your card when you shop online with this and other participating retailers. Simply complete the details below to activate this free security service.

**I think that's what it is, just checked on the official website for Santander and its about adding a password when using online transactions, only at a few participating retailers.

The second part must be the information tied to your credit/debit card, though be careful that the page is SSL secured.
