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.
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.

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