As others pointed out, the difference is that the local connection to the phone, together with the Webauthn+FIDO protocols make this resistant to phishing. That comes at the cost of needing Bluetooth, which isn't available on all computers. I.e. it's more secure than the prompt you have now, but that will at least work everywhere. The right tradeoff between the security and the convenience/availability is something that is very context-dependent, and different for each user. Hence the multiple options.
