Apple Pay also fills all of your address information when you buy online. You can tap Apple Pay, double click the side button and done. Trusted devices are the basis of Apple 2FA, not a phone number. All of your information stored with icloud (aside from email and calendar) can also be encrypted such that if you lose your recovery key and passcode, your data is gone forever. That’s the best online security available in a consumer device.

I own a SINGLE Apple device, a Macbook. The only option for 2FA is a phone number. And again, Apple Pay is not available to me because Apple can't be bothered to add Android support.
I came here saying crypto's completely device agnostic, app agnostic, open protocol experience of "scan a barcode, hit pay, wait 2 minutes" was ideal.
You have suggested an alternative that is proprietary, unavailable to most users of the world, and requires me trusting a company that again, can't offer me real two-factor auth protection for my Apple ID.
I'm sorry, it's not a serious recommendation.
EDIT1: To produce this screenshot, I had to login twice, once after another, in different dialog boxes, both of which let me edit my input after submitting the contents. And then the entire process stopped. Then I hit "Turn On" again and ... it's just spinning. I'm sorry, I can't take any of this serious.
