The emerging practice in the United States of employers asking for Facebook login details from prospective employees has prompted significant controversy. Some companies have made other requests such as asking job applicants to log in to their private profiles during interviews or become Facebook "friends" with a human resources manager. Facebook itself has posted a letter to users indicating that, in its opinion, it is a violation of Facebook's terms of use to share or solicit a Facebook password and warning employers that seeking access to Facebook accounts could result in unanticipated legal liability.
