AW: Mac OS 9 Idle Lock Bug

It's possible to set up the
Finder so that, if the current user goes idle, the screen will be
locked.  A simple dialog box is displayed stating that the system has
been idle for too long and a password must be entered.

You have two options.  Click OK and enter the password to return to
your session or click OK and click Log Out. It's possible to seize
control of Mac OS under certain conditions by clicking Log Out.

so you can log out the current user and quit all apps without having to
enter a password? i think this is the real security flaw, not apps which ask
wether you want to save changes.

Some applications have the "feature" of asking you if you're sure that
you want to quit.  For example, if connected to a UNIX host using
NiftyTelnetSSH, it will ask you if you're sure you want to disconnect
when the application quits.  Other applications with unsaved data will
ask if you want to save changes.  Most of these dialog boxes have OK
and Cancel or Yes, No and Cancel for options.  Hitting Cancel at any
of these "are you use" dialog boxes will stop the logout process and
return you to the current session.

which is useful if you hit quit and you actually don't want to quit (i know,
this is for silly lusers, but they exist). to quit an app without asking,
there had to be another event, which current apps wouldn't support.

Now, being primarily a UNIX user that also uses Mac OS for graphics
and Web page design, I realize that relying on Mac OS for physical
security is about as silly as relying on the Windows 95 password
"protected" screensaver for security.  I just figured that I'd point
out this small issue because the Mac OS 9 ads seem to be pushing the
added security benefits of upgrading to Mac OS 9 and its voiceprint
password protection.

well, it seems /this/ kind of protection doesn't work. however, if you shut
down the mac, you'll have to log in when booting.
