My point is that it doesn’t matter if Linux xan do this, the discussion was about a mobile phone that could do both biometrics and pin at the same time.

if you lack basic cognitive reasoning to the point that someone can configure PAM in a specific way on desktop linux, and that presumably, a phone running the exact same software suite, with no differences aside from graphical environment, somehow couldn't do this is actually just kind of sad.

Wait until you find out how monitors display color. They have three different colors, red green and blue, and somehow, that manages to make all the funny colors on your screen. But since you can't see the individual pixels with your naked eye, i guess that must be untrue now huh?
