ASP.NET Identity Feature:

What is the purpose of ASP.NET Identity?
The MVC project templates have been
updated to use ASP.NET Identity for
authentication and identity management.

some examples of ASP.NET identity which
can be used for authentication and identity
management. Third party login providers

Authentication Filters:
Available
What is the purpose of Authentication
Filters?
Authentication filters are a new kind of filter
in ASP.NET MVC that run prior to
authorization filters in the ASP.NET MVC
pipeline and allow you to specify
authentication logic per-action, per-controller,
or globally for all controllers. Authentication
filters process credentials in the request and
provide a corresponding principal.
Authentication filters can also add
authentication challenges in response to
unauthorized requests.
In Summary, Authentication filters can be
used to authenticate users by custom or third
party authentication providers

Filter Overrides Feature:
Not Available
Filter Overrides Feature:
Available
Why Filter Overrides Feature?
We can now override which filters apply to a
given action method or controller by
specifying an override filter. Override filters
specify a set of filter types that should not be
run for a given scope (action or controller).
This allows us to configure filters that apply
globally but then exclude certain global filters
from applying to specific actions or
controllers.

2. i.e., We can say in MVC 5 it’s now possible
to override filters on a method or controller
by specifying an override filter.
