Can I connect to the remote realm without having to log in?
No, you always need to authenticate.
Is there a way to get an anonymous user so that someone can connect to the remote realm?
There is still no built-in anonymous login or anonymous user, as the Realm object server does not support account binding or direct merging of independently created Realms.
As a simple workaround, you can now rely on password-based authentication. Then you will need to create the user once and you will be able to hard-code these credentials in your application.
