If only hackers and scam artists would adopt accessibility standards, we could go back to the simpler things. I agree account verification and 2FA can be brutal for AT users. Do you have a solution apart from everyone having a smartphone with face or fingerprint recognition? In the Mac world, when a required code is received via text, the computer or iOS device can automatically populate a code field if you are signed in with your Apple ID. This is the best solution I can I've seen.
If the 2FA code is sent via email, it will pass the requirements as it stands today, because that can be cut/pasted on the primary device. The big ban is on the manual transcription from one device to another.
