Humanity is moving towards a digital future where our assets, data, and everything else will be available digitally. 

There is now a need for a better authentication system, one where we can prove our identity without relying on third-party centralized companies like Google. 


And here's what I believe the future will look like 

Blockchain uses private keys, which are private texts known only to the owner, for authentication. It is a system not reliant on any third party; anyone can create a private key without even using a computer and own an account on the blockchain network. 

However, this cannot be our future because your digital ownership is tied to a single text that, if known to anyone, will make them the owner.


For example, you may allow $100 to be spendable using your hand, $200 by authentication using your eyes, or you may not even use your physical body but instead use a non-internet connected device with a code that allows authentication up to a certain amount. 

You may use a hand sign, voice command, or any combination of methods. The authentication might change by daytime or location—it could be anything. The best part is that no one will know how you authenticate yourself; you just do.


What I imagine is that there won't be a single authentication method but hundreds of authentication methods, and you can use a mix of them in any way, with no one knowing how you authenticate yourself.


One solution could be that the identifier of our identity should not be something digital that can be copied by anyone but something physical that is part of us, like our eyes, hands, or voice. 

However, I can't imagine a future where everyone authenticates everything with their eyes, always carrying their whole digital assets and identity with them, exposing them to kidnapping and $5 wrench attacks.
