How do Two-factor authentication (2FA) work? Why does it not work for all online purchase transactions?

When not for all purchases: you don’t update something that works.
1) it cost money and company like to not spend
2) that a critical business kind of business (well, they still don’t care about fraud and can cover it with all the money they make)
2) the number of products/software sthat use those network is really big and ALL of them would need to add it.
However, I’m still with you on that one. They could do a smooth transition like with the chip payment.
Not mandatory to use it, but usually using it increase the odd of a safe transaction.
Some are even using a CVV that change from time to time! I want that!
