Word about the Heartbleed bug spread widely and quickly, prompting many of us to change our passwords on numerous log-in sites. Have a tough time remembering all your passwords? Begrudge the time and effort it took to make the changes?

Protecting online data is an ongoing concern, and changing passwords routinely is a practice that would serve us all well. There has been talk of instituting an annual Change Your Passwords day, but a once-a-year change is probably not enough to alleviate the concern. Hackers, leaks, security fails and program vulnerabilities are part of our wired landscape.
