Installation of Identity on this Template and Razor Pages

[PPCMD]

I have made a project with this template. However, I wish to add functions to create and delete user accounts. Is Identity pre-installed with this template or do I have to install it separately? If the latter, how should I configure it?
Moreover, I would also like to know how I can create pages, like Razor pages, which do not have the URL "/blog/page". I know that Razor Pages are disabled in MVC projects, but is there a method to use both? Otherwise, can the default URL prefix (/blog/page/) be changed to something else (/info/page)?
Thanks in advance.
