Wordfence wfwaf-authcookie-(hash) This cookie is used by the Wordfence firewall to perform a capability check of the current user before WordPress has been loaded. This cookie is only set for users that are able to log in to WordPress. It allows the Wordfence firewall to detect logged in users and allow them increased access. It also allows Wordfence to detect non-logged in users and restrict their access to secure areas. The cookie also lets the firewall know what level of access a visitor has to help the firewall make smart decisions about who to allow and who to block.
Wordfence wf_loginalerted_(hash) This cookie is used to notify the Wordfence admin when an administrator logs in from a new device. It is only set for users who log in, and only if the site administrator has enabled the option “Only alert me when that administrator signs in from a new device”, or the similar option for non-administrator users. It helps site owners know whether there has been a user login from a new device.
Wordfence wfCBLBypass Wordfence offers a feature for a site visitor to bypass the country blocking feature by accessing a hidden URL. This cookie helps track who should be allowed to bypass the country blocking feature. When a hidden URL defined by the site administrator is visited, this cookie is set to verify the user can access the site from a country restricted by the country blocking feature. This will be set for anyone who knows and visits the hidden URL. This cookie is not set for anyone who does not know the hidden URL to bypass country blocking. This cookie gives site owners a way to allow certain users from blocked countries to visit your site, even though the country they are located in has been blocked.
