It seems the direction Google, Apple and Microsoft are all heading in is to own authentication and control access to our computers both at work and home.
Third party authentication technology has been around on Windows in one form or another for decades, but this is interesting because it's cloud based authentication that doesn't rely on corporate infrastructure.
It would be really nice if Google releasing this is a catalyst for an Open Source project doing something similar.
Chromebooks, Windows S (and RT before it), notarization of apps on MacOs could be helpful in an Enterprise environment to prevent malware, this is at the expense of freedom of choice.
I worry that the PC era is ending and we're drifting towards a future market more like consoles and mainframes where you never really own the platform that you paid for.
