Do we need alternative for 2FA?
I am 100% sure we need it!
We are becoming to attached to Google and services they offer, like Gmail, Youtube, Google 2FA, Google search.
They truck every single thing people are doing, and only way we can keep a bit off our privacy
is by slowly reducing usage of this services and gradually transition to alternative options we have.
you first need to prove there is actually something wrong with the current tools then argue about alternatives. i am personally not convinced with your argument here.
lets first look at how Google Authenticator works.
it is a very simple application that works offline and without needing Google servers or sending anything to them. it works based on your device's time and the password/key that you and the other party share. using that key you generate a number which acts as your 2FA.
now explain to me how are we relying on Google for any of it? it is not like Gmail that you need their server! everything happens inside your device and stored in your device.
besides if we assume we need an alternative, we definitely don't need a "cryptocurrency" for that! it doesn't even make sense to create one!!!
If you are talking about 2FA, and in specific TOTP
It has many flaws, and that is why they created better version U2F.
2FA Backup codes are sent online, they are probably not even encrypted,
and hackers can take control of password or backup.
You are trusting other party to save keep your secret code.
U2F is better because there is nothing shared over internet.
Hackers can not hack in to d2FA as there is no single point server that is keeping your secret.,
or maybe they can but in Quantum future.
