So I tried to log in to a specific site today (www.swtor.com) and to my surprise there were 3 names saved there that I've never seen before. I am the only one who uses this compter and I've never ever used such names to login anywhere. I got a little worried and this was the first place (after trying to goolge some info) I came to ask where the hell they came from. I'm hoping it's some kind of a bug but any ideas will be appreciated...
