I'm not convinced that it is at all possible to avoid using passwords going forward.

It will take a while, but passwords will be rarely used soon

Certificates are a form of password and I don't think they will go away, ever. And before you can get yourself a certificate to some server, you will first have to enter some credentials. So there's a server farm with 500 servers and you need to connect to server 237. How else are you going to do this if not by entering a password and then getting yourself a certificate?

And normal websites don't even make use of the awesomeness that are certificates, because that's a lot of extra effort on the side of the webmaster.

The mind is the only thing that can't be duplicated (for now). Any other system, be it biometric, physical token, or other, can be eventually duplicated.

The trick is to make it complex enough to take a long time to circumvent and change it before that time.

I'm not sure sure if you are talking passwords or biometrics, etc.

For passwordless options, duplication is only one problem. Once a biometric, for example, is duplicated, then it compromised and can't ever be secure again. It will be insecure whether either physically compromised or numerically compromised.

There are only a limited number of biometric options.
