What is the wfwaf-authcookie- cookie?
wfwaf-authcookie- is a cookie generated by Wordfence, one of the most widely used WordPress security plugins. Its full name includes a unique identifier (usually a hash) that differs per installation, which is why scans list it as "wfwaf-authcookie-" followed by variable characters.
The cookie is set by Wordfence's built-in Web Application Firewall (WAF), which runs directly on the site through the plugin rather than an external service. It appears in the browser when a user logs into WordPress (typically an administrator or editor), allowing Wordfence to recognize the session as belonging to an authenticated user.
What data it stores
The cookie stores information related to the user's authentication status with respect to Wordfence's rules — essentially a cryptographic marker the plugin uses internally to verify that requests come from a legitimate logged-in user rather than an anonymous visitor or a bot.
The exact value format can vary by plugin version and is not documented in detail publicly by Wordfence. The data stays on the site's own server (it is not sent to third-party servers) — Wordfence processes everything locally, within the client's own infrastructure.
What it is used for
The cookie's role is purely functional: it helps the Wordfence firewall distinguish authenticated users from other traffic, so it can apply different security rules (for example, more relaxed restrictions for a logged-in admin versus an unauthenticated visitor).
In practice, this cookie contributes to protecting the site against brute-force attacks, injection attempts, and other malicious activity, and has no connection to visitor tracking or advertising.
Does it require consent?
As a cookie strictly necessary for secure site operation, wfwaf-authcookie- does not require prior consent under Article 5 of the ePrivacy Directive (transposed in Romania via Law 506/2004) and does not fall under the GDPR consent requirements applicable to analytics/marketing cookies.
- The site owner should still list it in the cookie policy, under the "necessary/strictly necessary" category.
- It should not be included among the cookies awaiting visitor acceptance in the consent banner.
- It's good practice to disclose its purpose (security/authentication) and provider (Wordfence) in the publicly displayed cookie table.
How to block or delete wfwaf-authcookie-
A visitor can manually delete or block this cookie via browser settings (Chrome, Firefox, Edge, Safari — per-site cookie management), but doing so will log the user out of their WordPress account, since the cookie is tied directly to the authenticated session.
Because it is strictly necessary, a properly configured CMP should not block this cookie — doing so could break the WordPress admin panel. Platforms like CookieFix automatically distinguish strictly necessary cookies from those that genuinely require consent, blocking analytics or marketing scripts until the visitor consents while leaving functional cookies like this one untouched.
Frequently asked questions
It's a technical cookie set by Wordfence, a WordPress security plugin, used to recognize logged-in users and apply the appropriate firewall rules.
No. It's a strictly necessary cookie for security and authentication, processed locally on the site's own server, unrelated to advertising or visitor profiling.
No, since it's strictly necessary for secure site operation it doesn't require prior consent, but it should be disclosed in the cookie policy.
Its typical duration is 12 hours, after which it expires automatically and the user must log in again for Wordfence to recognize the session.
