According to a report, some of the most popular websites aren't taking password security seriously.More than 80 percent of websites that were examined had subpar password security standards, according to Dashlane's Password Security Roundup report.

Dashlane, a password management company, examined 80 websites across six categories: dating, e-commerce, travel, productivity, social utilities and security.

Overall, 51 percent did not lock accounts after 10 incorrect password entries, 43 percent accepted the most commonly used passwords such as "password" or "123456" and 86 percent did not meet the requirements to score high enough to be considered adequately safe, Dashlane said.

The way the sites were ranked allowed for them to score between minus 100 to 100. To be considered to have an adequate password policy a website needed a score of 50.

Match.com had the worst password policies, followed by Hulu and Overstock, which both tied for second worst. Other sites that scored poorly included Amazon, Groupon, Orbitz, and Victoria's Secret.

The site that scored the highest was Apple, said CNBC, which had a perfect score of 100. Hotmail came in second, followed by the Microsoft Store website and UPS.
