The man who wrote the book on password management has a confession to make: He blew it.
Back in 2003, as a midlevel manager at the National Institute of Standards and Technology, Bill Burr was the author of “NIST Special Publication 800-63. Appendix A.” The 8-page primer advised people to protect their accounts by inventing awkward new words rife with obscure characters, capital letters and numbers—and to change them regularly.
The problem is the advice ended up largely incorrect, Mr. Burr says. Change your password every 90 days? Most people make minor changes that are easy to guess, he laments. Changing Pa55word!1 to Pa55word!2 doesn’t keep the hackers at bay.
The Man Who Wrote Those Password Rules Has a New Tip: N3v$r M1^d!
IT’S GETTING EASIER to secure your digital privacy. iPhones now encrypt a great deal of personal information; hard drives on Mac and Windows 8.1 computers are now automatically locked down; even Facebook, which made a fortune on open sharing, is providing end-to-end encryption in the chat tool WhatsApp. But none of this technology offers as much protection as you may think if you don’t know how to come up with a good passphrase.
A passphrase is like a password, but longer and more secure. In essence, it’s an encryption key that you memorize. Once you start caring more deeply about your privacy and improving your computer security habits, one of the first roadblocks you’ll run into is having to create a passphrase. You can’t secure much without one.
In this post, I outline a simple way to come up with easy-to-memorize but very secure passphrases. It’s the latest entry in an ongoing series of stories offering solutions — partial and imperfect but useful solutions — to the many surveillance-related problems we aggressively report about here at The Intercept.
