Biometrics "not reliable": at Heathrow Airport they have iris scanners.
Once when you enter the security area, a second time when you are getting
ready to go into the gate area. I didn't match between the first time and
the second time ... how could that be? Well, I wear progressive-lens
glasses. Different angles, different magnifications. I spent 10 minutes
peering into the thing tilting and re-tilting my head to get it to match the
first scan ... better than being hauled away by security officers ...

It's time for biometrics passwords ...for PCs and mainframes ...
Or other means of security behind passwords. It can be also a token.
In order tolog on you have to provide password and the code displayed by
the token. The token can have a keyboard for PIN entering.
So stolen password is not a problem. Stolen/lost token is not a problem.
Stolen password & token is still not a problem (for tokens with PIN).
Such solution is available for many years, also on z/OS.
The only problem is a cost. Hint: cost of tokens + software/hardware is
not TCO.
BTW: I prefer tokens over biometrics for the following reasons:
1. Biometrics is not reliable. Depending on the method used it could
cause "false failures", for example a fingerprint after some injury
cannot be recognized. Same about face recognition (BTDT), etc. So
usually biometrics is backed up with ...regular password.
2. Some biometrics are slooow. I saw room access control system which
had to be disabled, because there were long lines (queues) to the doors.
3. Some biometric devices built in your PC can be hacked, or in other
words, your PC will receive OK from phony device instead of real one.
