      By default, this will only store the credentials locally without

      Arguments:
          anonymous: (string, optional) Can be "must", "allow", or "never".
              If set to "must" we'll always log in anonymously, if set to
              "allow" we'll only create an anonymous user if the user
              isn't already logged in.
          key: (string, optional) authentication key.
          relogin: (bool, optional) If true, will re-prompt for API key.
          host: (string, optional) The host to connect to.
          force: (bool, optional) If true, will force a relogin.
          timeout: (int, optional) Number of seconds to wait for user input.
          verify: (bool) Verify the credentials with the W&B server.
