Why (

real bewildered look on my face)? QR code is just a specific mapping of secret code expressed in characters. I can’t tell the difference between them when it’s a matter of choosing backup. But, at the same time, QR code ensures better data security when transferring across devices.

When the map is broken, you have nothing to recover your 2FA but with secret key, if one of characters is blurred or broken, you still can guess it from the leftover of broken character.

Remember that there are two layers of backup: backup codes, and 2FA secrect key (or bar code). I advise you to do backup for both of them, or if you choose only one to backup, it should be 2FA secret key, not barcode. With secret key, you will be easier to guess if character, figure are blurred a little bit but with bar code, it is almost nothing to do. Of course, saving 2FA secret key backups as best as possible is the must thing to do.

Im using it as back up for my some of my crypto asset wallet. How can you say QR code has likely more potential than in character type? When you use it for transaction, simply the confirmation would be guaranteed unlike character that you will used a copy paste method that have malware changing the address when you paste it.

Let differentiate between backup and transaction. What I meant is backup, not for transactions. For transactions, you should check a few first and last charaters. Checking a few in middle or whole characters if you want to do so.
