3DS is 2FA and PayPal most definitely has it, it's just that they protect the customer regardless of 2FA.

3DS is 2FA and PayPal most definitely has it, it's just that they protect the customer regardless of 2FA.
3DS is not just 2FA, but it has an option to shift liability to the card issuer in case of card-stolen disputes. Our fraud has come to near 0 once we started 3DS enforcement. 1% of 3DS transactions don't lead to a liability shift, and in such cases, we flag those transactions and call the customer to get more forms of identification that they own the card.
With PayPal - beyond ownership of email address (which is already compromised), there's nothing else to validate against.
