well, then of course, you can ask any question to clear things up but a basic understanding of how private keys in crypto work is necessary. Otherwise, the take-home message is: biometric login is not the same as biometric tracking. People said they would never use biometrics for logging in into Steemit "because they don´t want their biometrical data to be stored" but this is non-informed BS.

biometrics are a password-substitute and the password is as safe as a normal password/input is. Your password is not stored openly anywhere, your fingerprint is not saved openly anywhere.

But besides of ease of use, the main reason to use biometrics is to identify unique users and to tell them apart from bots and multiple accounts. This will prevent all the abuse issues we have right now.

and when you master to identify unique users you can utilize democratic voting instead of plutocratic voting. Right now votes on proposals are stake weighted, so one rich idiot with bad intents can counter 1000 votes with good intents regarding the future of the platform. And the value of a platform is directly dependent on the number of happy users, therefore decisions should be made in the interest of the users/customers and not single wales.
