Simple passwords not enough as perils of online world growBy ANICK JESDANUN Associated Press
To access her bank account online, Marie Jubran opens a Web browser and types in her Swedish national ID number along with a four-digit password.
For additional security, she then pulls out a card that has 50 scratch-off codes. Jubran uses the codes, one by one, each time she logs on or performs a transaction. Her bank, Nordea, automatically sends a new card when she's about to run out.
As more Web sites demand passwords, scammers are getting more clever about stealing them. Hence the need for such "passwords-plus" systems.
Scandinavian countries are among the leaders as many online businesses abandon static passwords in favor of so-called two-factor authentication.
"A password is a construct of the past that has run out of steam," said Joseph Atick, chief executive of Identix, a Minnesota designer of fingerprint-based authentication. "The human mind-set is not used to dealing with so many different passwords and so many different PINs."
When a static password alone is required, security experts recommend that users combine letters and numbers and avoid easy-to-guess passwords like "1234" or a nickname.
Stevan Hoffacker follows those rules but commits a different faux pas: He uses the same password everywhere, including access to multiple e-mail accounts, Amazon.com, The New York Times' Web site and E-ZPass electronic toll statements.
In such cases, should hackers or scammers compromise one account, they potentially have one's entire online life.
"This is one of these things that if I stop and think about it, it is not good, but I do my best not to stop and think about it," said Hoffacker, an information technology manager in New York.
But it's difficult to remember dozens of strong passwords. Alternatives include writing them down on a sticky note attached to a monitor or in an electronic spreadsheet — practices security experts also deem unsafe.
Software such as Symantec's Norton Password Manager and Apple Computer's Keychain help store passwords in secure, encrypted form. But if you compromise the master password, you're out of luck. Your entire collection is gone.
Many sites, meanwhile, will e-mail passwords insecurely — without encryption — if you forget. A site called www.BugMeNot.com even encourages users to share passwords for nonfinancial sites like newspapers.
The tools of password harvesting are many:
Keystroke recorders secretly installed at public Internet terminals can capture passwords, as can "phishing" e-mails designed to trick users into submitting sensitive data to fraudulent sites that look authentic. Computer viruses are also programmed to harvest passwords, and some software guesses passwords by running through words in dictionaries.
Although analysts have no hard figures on password-specific fraud, they blame insecure passwords for unauthorized financial transfers, privacy breaches and even the hacking of corporate networks.
With two-factor authentication, a password alone is useless.
"We will never play the fear factor here, but still it stays a fact that with our products, phishing is no longer an issue," said Jochem Binst of Vasco Data Security International.
The Belgian company issues devices the size of pocket calculators or keychains. You type your regular password into the device for a second code that is based on the time and the unit's unique characteristics. That's the code you type into the Web site.
Someone who steals your device won't have your password; someone who steals your password won't have your device.
MasterCard International has been testing similar systems in Britain, Germany and Brazil. Swipe a credit card with a smart chip into a special reader, enter your PIN and obtain a password good only once at Office Max, British Airways and a dozen other merchants.
In the United States, use of two-factor authentication remains limited. RSA Security has several products, including RSA SecurID, but they are primarily issued to employees for remote network access and to customers with high-value portfolios.
"There's a delicate balance between maintaining security but also providing customers with ease of use," said Doug Johnson, senior policy analyst at the American Bankers Association.
