> How will a website be able to scan my phone's screen?
Using your webcam. However from the comments it seems that there are a lot of devices without a webcam so my idea will not work.

I've no idea how typical I am in this regard, though.
Could you turn the idea on its head? Could the website display the QR code and the phone scan it, as per WhatsApp and many others? Or perhaps the phone just displays the note ubiquitous "random raccoon" type wordset for the user to enter into the website?
I'm probably missing the point of your idea.

It was mainly a way to do 2FA with a phone but no SMS/internet on phone. However it looks like TOPTs solve this probelem.
No problem, good luck :) Is good to see someone experimenting in this area and asking for advice to stay on track.
