{% csrf_token %} is a tag that is used in Django templates to prevent cross-site request forgery (CSRF) attacks.
A CSRF attack occurs when a malicious website causes a user’s browser to perform an unwanted action on a trusted site when the user is authenticated.
{% csrf_token %} generates a secret and unique token on the server-side when rendering the page and makes sure to cross-check this token for any requests coming back in.
If the incoming requests do not contain the token, they are not executed. This way, {% csrf_token %} protects your site from unauthorized actions by verifying that the user actually intended to submit the form.
{% csrf_token %} is important because it helps you secure your web application from malicious attacks that could compromise your data or functionality.
Without {% csrf_token %}, an attacker could trick a user into submitting a form that performs an action they did not intend, such as deleting their account or transferring money to someone else.
