To signup for Google Webmaster Console, just register for it in your Google account you already use for adsense. If you don’t have an account with Google, signup for one so you can use Adsense, Webmster console, Gmail, and other things. The full options of the console are available to those who get their site verfied, which only takes a creation of a specified html file or a meta tag at your site.
