Hmm, I don't much like all this extra complexity in the struct.  Why not just
set an empty username if there is no username for this form?  Or, you could
reverse the order of the username and password fields so that the password field
comes first.  Then, if basic_data.fields.size() is 1 there's only a password,
and no username.

I've changed to reverse the order of username and password.

+  //    - You should set the username basic_data.fields[0]

+  // 2. If you would like to set only a password in it,
+  //    - You should set the password basic_data.fields[0]
   FormData basic_data;
   LoginCollection additional_logins;
