A recent survey of over 2,000 adults conducted by Harris Poll on behalf of Dashlane, a "leader in online identity and password management," found that nearly 40 percent of Americans would give up sex for an entire year if it meant they'd never have to worry about being hacked. Huffington Post reports: 40 percent of people also said they'd give up their favorite food for one month in the name of peace of mind online. If all of this sounds drastic, the truth is that it probably is. The single biggest thing people can do to help keep their online identity safe is probably the easiest -- a solid password. 10 years ago, anti-virus was the primary method of online security. But since the Internet has left the desktop and is on laptops, tablets, and cell phones, and since so many people now use the cloud for backing up their sensitive data, following proper password protocol is critical. Of course, having a solid password doesn't do a lot of good if you're giving it out to people. And nearly 50% of people have shared a password to an e-mail account or to an account like Netflix with a friend or had a friend share theirs (which is a surprisingly high number when you consider that 4 out of 10 people said that sharing an online social media password was more intimate than sex). A look at the password habits of Americans showed that about 30% have used a pet's name, almost 25% have used a family member's name, 21% a birthday, and 10% each have used an anniversary, a sports team, an address, or a phone number. So if you just know a few basic, personal details about someone, you've got a decent chance at cracking their password. The study also revealed some interesting data in that younger Americans (those age 18 to 34) who grew up online are far more trusting with passwords than older generations, and married people are less likely to part with passwords than single people.
