[kwlug-disc] Heartbleed affected sites

unsolicited unsolicited at swiz.ca

That's my point - it DOES hurt to change it.

Time consumption to do so, and time wasted later trying to remember what 
you changed it to -this- time. Or chase down how you recorded it (e.g. 
browser cache / password lookup). Now repeat for every other place 
you've been encouraged to (pointlessly) change your password as well, 
which of course you did because the media knows all.

Now multiply by number of users out there. And again by number of 
accessing devices. What a waste of resources.

This is my issue - all very well to take corrective action to known and 
quantified issues, but not so to send everyone to chase their tail 
everywhere 'just in case.' The I.T. industry could and should do a 
better job for its users. I.T. is a tool, not an end in itself. The tail 
should not be wagging the dog.

-----

Your note makes me wonder ... wherefore OpenID on all this? (In the 
sense of being a single password.) And I wonder if (some day?) OpenID 
could go change all your passwords for you, and the user need only 
change their OpenID password.

Given your note, I'm guessing that makes some sense to you too, if two 
factor authentication is used for OpenID there. [OpenID == (set of 
OpenID like services, which seems to more and more include gmail accounts)]
