I just signed in to Tomsharware via Google+ because I forgot my password to Tomshardware. This is my first time using Google+ on a third party website. Does it recognize my account via the email address... and then log me into my account matched with the email address? Does a website like Tomshardware have to have an agreement with Google or Facebook to use this feature? Are my contacts and email safe while logging into third party sites like this?

Thanks

Steve
