What is the purpose of a CSRF token?

Explanation:
CSRF tokens are used to ensure that requests that change server state actually come from the legitimate site and user. The server generates a unique token for the user’s session, embeds it in forms or AJAX requests, and requires that token back with state-changing actions. If the token is missing or doesn’t match, the server rejects the request, preventing a malicious site from making unintended changes on behalf of a logged-in user. The purpose is specifically to defend against cross-site request forgery, not to encrypt communications, identify a device, or bypass login.
