Google engineers have been experimenting with hardware that would act as a master key for online services. The idea is to prevent remote hackers from accessing online accounts through stolen usernames and passwords. Some Web services already offer this type of security through two-step authentication. A ring or other contact-based device would help protect users from faraway hackers, but it’d be easier to steal by spouses, co-workers or children. Google’s engineers admit they might still need to require passwords, but those passwords wouldn’t have to be as complex as today’s hacker-proof formulas.”]
