narramissic writes "We all know well the perils of password reuse. But what about the information used to reset passwords? Many sites use a standard set of questions — your mother's maiden name, the name of your best friend, what city you grew up in, or what brand your first car was. And you probably have a standard set of responses, making them easy to remember but not very secure. 'The city you grew up in and your mother's maiden name can be derived from public records. Facebook might unwittingly tell the name of your best friend. And, until quite recently, Ford with its 25% market share had a pretty good chance of being the brand of your first car,' says security researcher Markus Jakobsson. But 'password reset does not have to be a weak link,' says Jakobsson. 'Psychologists know that people's preferences are stable — often more so than long term memory. And very few preferences are recorded in public databases.'"
