[kwlug-disc] Heartbleed affected sites

Don't get me wrong. On the scale of things you should do in response to
Heartbleed, changing your password, IMHO, is pretty low on the list.

Turning on two-factor authentication is way higher.  Admittedly, not as a
direct result of Heartbleed, but out of a realization that you can't trust
servers to keep your secrets.

And installing and using a password manager is also important out of a
similar realization: you are going to need to change your password.
Rainbow tables and whatnot mean you can't trust yourself to create password
for yourself that is unique and memorable and safe.  You should get in the
habit of changing your passwords, and heartbleed is as good an excuse to
get started than any of the many, many other "OMG change your password"
scares of the last few years.

And if you don't care and don't want to bother, that don't bother me
none.   It's your money/reputation/time/whatever.

Darcy.
