All of us who are heavy users of computers and the internet know that we get drowned in the number of passwords we need and that it is hard to keep track of them.
James Fallows describes what he learned after his wife’s Gmail account was hacked and gives a list of suggestions for passwords.
The science, psychology, and sociology of creating strong passwords is a surprisingly well-chronicled and fascinating field. On The Atlantic‘s Web site, we will describe some of the main strategies and the reasoning behind them. Even security professionals recognize the contradiction: the stronger the password, the less likely you are to remember it. Thus the Post-it notes with passwords, on monitor screens or in desk drawers.
But there is a middle ground, of passwords strong enough to create problems for hackers and still simple enough to be manageable. There are more details on our site, but strategies include:
- Choose a long, familiar-to-you sequence of ordinary words, with spaces between them as in an ordinary sentence, which more and more sites now allow. “Lake Winnebago is deep and chilly,” for instance. Or “my favorite packer is not brett favre.” You could remember a phrase like that, but a hacker’s computer, which couldn’t tell spaces from characters, would see only one forbiddingly long password sequence.
- Choose a shorter sequence of words that are not “real” English words. I once lived in a Ghanaian village called Assin Fosu. I can remember its name easily, but it would be hard to guess. Even harder if I added numbers or characters.
- Choose a truly obscure, gibberish password—”V*!amYEg5M5!3R” is one I generated just now with the LastPass system, and you’re welcome to it—and then find a way to store it. Having it written down in your wallet is one, though the paper it’s on shouldn’t say “Passwords” at the top. The approach I prefer, and use for some passwords, is to entrust them to online managers like LastPass or RoboForm. Even if their corporate sites were hacked, that wouldn’t reveal all your passwords, since the programs work by storing part of the encoding information in the cloud and part on your own machine.
At a minimum, any step up from “password,” “123456,” or your own birthday is worthwhile.
Finally, use different passwords. Not hundreds of different ones, for the hundreds of different places that require logins of some kind. The guide should be: any site that matters needs its own password—one you don’t currently use for any other site, and that you have never used anywhere else.
“Using an important password anywhere else is just like mailing your house key to anyone who might be making a delivery,” Michael Jones of Google said. “If you use your password in two places, it is not a valid password.”
I asked my experts how many passwords they personally used. The highest I heard was “about a dozen.” The lowest was four, and the norm was five or six. They all stressed that they managed their passwords and sites in different categories. In my own case, there are five sites whose security really matters to me: my main e‑mail account, two credit-card sites, a banking account, and an investment firm. Each has its own, good password, never used anywhere else. Next are the sites I’d just as soon not have compromised: airline-mileage accounts, Amazon and Barnes & Noble, various message boards and memberships. I have two or three semi-strong passwords I use among all of them. If you hacked one of them you might hack the others, but I don’t really care. Then there is everything else, the thicket of annoying little logins we all deal with. I have one or two passwords for them too. By making it easy to deal with unimportant accounts, I can concentrate on protecting the ones that matter.
Seems like good advice.
