An Open Letter to Web Sites Where I have a User Account (All 162 of You)
Congratulations on your new certificates. I'm very excited to change my passwords and all my security questions at each of your sites in the next few days… and to keep changing them every few months for the rest of all of eternity.
I know this "Heartbleed" thing has been a real drag for everyone, but in its wake can I ask for a few simple things moving forward? I think it's a pretty reasonable list:
1. I'd like to be able to use more than 9 characters in a password. I'm looking at you Discover. Is space on your server so dear that an extra dozen characters or so would kill you?
2. I'd like all special characters to be OK. Really, if I can type it on a computer keyboard, you ought to be able to deal with it. It's 2014. Do you realize that if I can use symbols and special characters, my password can be shorter and just as secure? An 11 character password made up of all available characters has the same 80-bit security as a 14 character password made up of only case sensitive alphanumeric characters.
3. I'd like to know up front what your particular parameters for acceptable password length and composition are. In other words, when you tell me "At least 7 characters/1 Number" it's of no use at all when I enter 30 characters, and then you tell me that's too many. And then I enter 24 characters and again you tell me that's too many. How about just telling me "at least 7 and no more than 20?" And whether or not "special characters" are OK. Thanks CVS. Changing my password with you was almost as much fun as playing Candy Crush, and just as challenging.
4. If I want to say that my mother's maiden name was "0(jK1bBn," what's it to you? To me, it's better security than posting all kinds of personal information to be stolen by hackers the next time you leave the hen house open. Just like having a different password at every site, I kind of like too have different security question answers as well.
Finally, maybe think about not hiding the "sign out" button in a different place on every single site. If I want to play "Where's Waldo," there's an app for that.
Sincerely yours,
Rob Falk

Annoyed By Facebook's Automatically Playing Videos?
Turn them off!
Just go to "Settings" (a little triangle in the upper right part of your window will open a drop down menu that takes you there) and look for "Videos" in the left column. (Mac users will need to use Chrome or Firefox to make the change. For unknown reasons, the "Videos" setting doesn't show up in Safari, although once you change the setting, it will work on all of your browsers.)
Make the change by clicking on "Videos" and choosing "Off"
Unfortunately, you'll need to make separate changes to your phone in order to stop the pesky buggers from running by themselves there, at least on Wi-Fi. Cousin Markie doesn't let us turn them off entirely, but at least they won't chew up your data.
Android Users: Open Facebook, open the left sidebar, and tap "App Settings."Check the "Auto-Play Videos on Wi-FI Only" box.
iOS Peeps: Open the "Settings" app, find "Facebook" (down below "Game Center") and then click on "Settings." Click the toggle next to "Auto-play on Wi-Fi Only" so that the toggle shows green.

Your Password WILL be Hacked. Not If, When. Fight Back.
Just this week, a well-meaning financial planner sent an email blast to advise his clients to change the passwords to all their web accounts, including the investment accounts that he managed. So far, so good… He suggested that his clients use a different password at each website (good.) Unfortunately, he suggested that they use a simple formula (horrible.) He wrote:
“I take the site name for example "gmail", capitalize the first letter, and then add "my own" 3 or 4 digit code, for example "1234" (but do not use this sequence as it is easy to break) . . . so applying the formula, the password would be "Gmail1234". Similarly, if I were to be using PenPal, it would be "Penpal1234" or "Pen1234.”The problem with this approach, is this: If I’m a hacker and I manage to get hold of one of his usernames and passwords, for instance the aforementioned “Google1234,” I would immediately try the same username with “Amazon1234,” “Chase1234,” “Citi1234,” “UBS1234,” “Paypal1234,” etc., at those sites. How am I doing so far?
For a fascinating (and depressing) explanation of why this method of password management is only a tad better than just going with “qwerty” at all of them, read Why passwords have never been weaker—and crackers have never been stronger at ars technica. It’s long and complicated. (And it's a couple of years old, meaning the situation is worse now.)
If you don’t care to dive in, then let me summarize: the guys who are cracking passwords are smarter than you are. They are using supercomputers, and can cycle through 6.2 billion combinations of letters, numbers and characters every second. They are working off of a dictionary of more than 60 million words. Every time a web site is hacked and a list of passwords is obtained, the hacking world gains even more knowledge of the passwords we use and how we use them.
This is what it’s come down to: Given enough time, your password will be hacked. All you can do is make it take long enough that you have reasonable time to keep changing your password before it is hacked.
Every one of your passwords needs to be randomly generated by a computer, and have a minimum of nine characters to make brute-force cracks infeasible. You need to change them all every three or four months.
Now is also the time to enable two-factor authentication at every website that offers it. With two-factor identification, even if someone succeeds in hacking your password, they won't be able to log in to your account from a device that you haven’t already approved. The log in won’t be allowed until after you receive a text message on your cellphone with a code, which must then be entered in addition to the password. An excellent list of sites offering two-factor authentication is found here. And remember, as good as two-factor identification is on the sites that have it, it does nothing to prevent that hacked password from being used at another site that doesn't have two-factor protection. Which is why, class repeat after me, "we use a different complex random password at every single site."

These Sites Don't Use SSL and Were Never Vulnerable to Heartbleed
According to data found at the Washington Post, the following is a list of 512 websites that are not vulnerable to the Heartbleed bug as of 12:00UTC, April 8, 2014. These websites don't use SSL and so they were never vulnerable to the Heartbleed bug. Nonetheless, it would not be a bad idea to change all your passwords. Save this list for last :-)
