Saw this yesterday, and out of an abundance of caution I spent nearly 2 hours changing all of my passwords to random, complex 16-24 digit ones. The use of a password management tool (1Password, LastPass) makes the password generation, storage and usability possible. Hell, even Apple's embedded password manager will do this for you.
If y'all are still re-using passwords or writing them down on scraps of paper under your mouse pads, you're simply stupid and deserve whatever misery digital life throws atcha.
