Goodbye, passwords--you aren't a good defense

By Randall Stross

The best password is a long, nonsensical string of letters and numbers and punctuation marks, a combination never put together before.

Some admirable people actually do memorize random strings of characters for their passwords--and replace them with other random strings every couple of months.

Then there's the rest of us, selecting the short, the familiar and the easiest to remember. And holding onto it forever.

I once felt ashamed about failing to follow best practices for password selection--but no more. Computer security experts say that choosing hard-to-guess passwords ultimately brings little security protection. Passwords won't keep us safe from identity theft, no matter how clever we are in choosing them.

That would be the case even if we had done a better job of listening to instructions. Surveys show that we've remained stubbornly fond of perennial favorites like "password," "123456" and "LetMeIn." The underlying problem, however, isn't their simplicity. It's the log-on procedure itself, in which we land on a Web page, which may or may not be what it says it is, and type in a string of characters to authenticate our identity (or have our password manager insert the expected string on our behalf).
