Comcast (NASDAQ:CMCSA) has added an auto-login feature to its Xfinity TV multiscreen video service. Dubbed Home Pass, the feature is designed to automatically login Xfinity TV and Internet customers accessing the Xfinity.com/TV website from within their home, with no need to sign in with a user name and password to access TV Everywhere content.The MSO trialed the feature during the London Olympics and March Madness 2013 and is now rolling it out permanently. Comcast says it is looking at ways to extend Home Pass to additional platforms in the future.
