Randomized keypads are for touchscreens, although like you said sort of not common for desktop workstations.
Just comparing a password to biometrics though on say a laptop or desktop, there is the major drawnback that you can be forced either knowingly or unknowingly to put in a biometric to unlock a device. It would be easier to circumvent then a standard password (at my company and the clients we work with, 16 characters is standard) with an encrypted hard drive.
This is all deduction ive made from other things I know to be true though, if you happen to know of a resource that explains both methods of securing g a workstation and the risks associated, I’d love to read it.
I also do agree overall that password less makes the most sense now, as people are never going to get better at making secure passwords and remembering them.
