51% of Computer Users Share Passwords 117
An anonymous reader writes Consumers are inadvertently leaving back doors open to attackers as they share login details and sign up for automatic log on to mobile apps and services, according to new research by Intercede. While 52% of respondents stated that security was a top priority when choosing a mobile device, 51% are putting their personal data at risk by sharing usernames and passwords with friends, family and colleagues. The research revealed that consumers are not only sharing passwords but also potentially putting their personal and sensitive information at risk by leaving themselves logged in to applications on their mobile devices, with over half of those using social media applications and email admitting that they leave themselves logged in on their mobile device.
Encouraged by a lot of places. (Score:4, Interesting)
A lot of the bigger, more frequently-used services actually encourage this. The best example I can think of is Netflix, which allows you to have separate profiles for family members but requires that everyone use the same user/pass to log in. I don't know why they couldn't just have individual passwords for the same account - at least that way I could avoid my mom trying to get everyone in the family to watch Sherlock ("Oh, I didn't see it on your watched list! You should try it!").
Amazon's Kindle app does pretty much the same thing, though it's not directly encouraged - you can log into your Kindle account from several different devices at once, effectively allowing people to share their books with anyone they trust enough. I think this is actually worse than Netflix, because most of the time you're using the Kindle app on a mobile device that can easily be lost or stolen.
The only company I've seen do sharing well is Valve, which has Steam Family Sharing that allows you to "lend" people your account without actually needing to tell them your password.
