Scanning a QR code by hand is easy when you don't have the phone handy. (sarcasm)

Actual OTP should allow you to print out or write down a set of codes.

That's way different from "I don't want to give out my phone number".

Both are impossible when not having a phone.

It's non sequitur.

"I have a phone number but don't want to give it out" is different than "I don't have a phone".

But hey, there are 2FA devices you can use instead.
