How it Works

  • user registers with an OpenID system in a given domain like they would with any other account
  • site under this OpenID domain will then give the user the option to sign in using this system
  • site contacts its external OpenID provider in order to verify that the login credentials supplied by the user are correct
  • large companies use their own OpenID systems
