A report released by the online security firm SplashData today found the most commonly used by global Internet users were "123456" and "password" in 2015 -- unchanged since 2011.
The fifth annual report by SplashData was compiled from more than two million leaked passwords during the year, and showed little change.
Despite the introduction of some new and longer passwords required by some websites, "the longer passwords are so simple as to make their extra length virtually worthless as a security measure," the company said in a blog post.
Other popular password are based on standard keyboard patterns like "1qaz2wsx" (first two columns of main keys) or "qwertyuiop" (top row of keys) but are "based on simple patterns that would be easily guessable by hackers," SplashData said.
