How to does the token prevent CSRF attack?
To prevent CSRF attacks, use anti-forgery tokens with any authentication protocol where the browser silently sends credentials after the user logs in. This includes cookie-based authentication protocols, such as forms authentication, as well as protocols such as Basic and Digest authentication.
Using a cookie to provide the CSRF token to the client does not allow a successful attack because the attacker cannot read the value of the cookie and therefore cannot put it where the server-side CSRF validation requires it to be.
