and make signing in even easier ?

because ive been on some websites that let you sign in/up through steam

not entire sure how it works buts its all safe and legit

and best way know of it legit is to go to steam 1st log in there then click the log in through steam link and if it doesn't already have you logged in and showing you this page i guess http://i.imgur.com/X9mgjKa.pngthen its fake
