What is passport.mobilenations.com and why is it taking login info for AndroidCentral suddenly?

Noticed it because my browser password manager wasn't working all of a sudden for this website.

MobileNations is the primary name for Android Central, WPCentral, Crackberry, webOS and iMore.
Basically if you go to mobilenations.com you have the option to go to any of the 5 site above.. I my self am a long time past member of crackberry, also use imore and androidcentral. Instead of having a login for each site, you can have a passport that allows login for all 5 site..
