The Seattle Times: Business & Technology: AOL offering users second layer of security "Passwords alone won't be enough to get onto America Online (AOL) under a new, optional log-on service that makes AOL the first major U.S. online business to offer customers a second layer of security.
The so-called two-factor authentication scheme, being unveiled today, will cost $1.95 a month in addition to a one-time $9.95 fee. It is initially targeted at small businesses, victims of identity theft and individuals who pay a lot of bills and conduct other financial transactions through their AOL accounts.
Subscribers get a matchbook-size device from RSA Security displaying a six-digit code that changes every minute. The code is necessary to log on, so a scammer who guesses or steals a password cannot access the account without the device in hand."
