As I know, if you use Role Management, it doesn't need store roles into database. Do you mean you want to authenticate users without database? If so, you could use Forms Authentication Credentials. For more information, please refer to the below link.
However, when you want to add new users, this way is hard to add. I suggest that you could use ASP.NET Identity with MVC. Please check the below article.
Hope this could be helpful to you.
