I was raised that physical access trumps all security measures (except
properly applied crypto). I fail to see how this significantly affects
security (except for laptops).
We're not talking about passwordless accounts, but rather bypassing
the password for physical access. I can see how this would be useful
for public computers such as libraries and kiosks. Perhaps a school
computer has a default passwordless logon for students, and allows
teachers to login w/ their own account/password.
Our users are not idiots, despite how much some of you seem to think
they are. That passwordless logons have privacy implications is quite
obvious, even to non-technical users. It also seems that there could
be benefits and applications for such a feature.
However, this should also be considered in light of the requests to
auto-login for gnome-keyring. It seems that it would be more correct
to distinguish between password/passwordless logons for that spec.
Anybody who tells me I can't use a program because it's not open
source, go suck on rms. I'm not interested. 99% of that I run tends to
be open source, but that's _my_ choice, dammit.
