It doesn't hurt and is a good approach, the code generated when using MVC template is not bad but most likely will need changes (according to requirements of your project).
if you need basic authentication sure account controller will do the trick and you can enhance the code if you need to.
if you want something more custom, let us know what you are trying to achieve and we can try to suggest options
