Coincidentally I set up 2FA on Amazon yesterday. I am disappointed they do not give you backup codes, nor do they support FIDO U2F. I made sure to keep a copy of the secret token in case anything happens to my phone I can set it up again. The way I do it is to scan the barcode in a reader first, save the token, then scan it in an authenticator app to install it.
