Web API and Attribute routing

Question

I am new in web api and attribute routing. just read a article from here. http://www.binaryintellect.net/articles/a2bf5c05-18a6-44b3-9f73-5896b40f0dff.aspx

see their attribute routing for web api action

[Route("api/[controller]/Logout")]
[HttpPost]
public IActionResult Logout()
{
    HttpContext.SignOutAsync(
CookieAuthenticationDefaults.AuthenticationScheme);
    return new ObjectResult("Success");
}

I have very basic questions. this attribute routing is ok [Route("api/[controller]/Logout")] controller name should be wrapped in {} or [ ] ?

Is it mandatory that when work with token then we need to work with identity?

can't we generate token if we work with form authentication ?

I am very beginner developer. so please help me with knowledge.

Thanks

For convenience, attribute routes support token replacement by enclosing a token in square-braces ([, ]). The tokens [action], [area], and [controller] will be replaced with the values of the action name, area name, and controller name from the action where the route is defined.

The [controller] token is replaced with the name of the controller where the action is defined in.

See Token replacement in route templates to learn more about that.
