Then I don't think you understand the various "factors" of security. I'd advise you to re-read the last line of my post that you replied to where I explained them. "What you are" is a completely valid factor for 2fa, when combined with either "what you have" (a token) or "what you know" (a password).

People need to stop complaining about biometric security if they don't understand the basic concepts of security in the first place. Re-read my first post and this one, and if you're still confused, look into factors of security. Hopefully you can stop parroting this nonsense that fingerprints are not a valid factor in 2fa.
