What is it for?
Session identifier created by PHP to remember what a visitor does from page to page (login, cart…). It disappears when the browser is closed.
What does it look like?
The value is a random string of about 26 to 32 characters. It contains no personal data by itself.
How to see it in your browser
Open your site, press F12, then choose the “Application” tab (Chrome, Edge) or “Storage” (Firefox). Under “Cookies”, select your site’s address: the PHPSESSID cookie appears in the list if present, with its value and expiry date.
What does the rule say?
A cookie strictly necessary for the requested service does not require consent. It should still be listed in your cookie policy.
How to prevent it before the choice
Nothing to block if it only serves the site’s operation. Avoid starting a session for visitors who do not need one.
How OpenCookies handles it
OpenCookies does not block this cookie: it is needed for operation. The test still lets you see which cookies are set before any choice.

Frequently asked questions
Does it need to be listed in the banner?
A strictly necessary cookie needs no consent, but should be listed in your cookie policy.
Why does it appear on a site with no login?
Because PHP code started a session, sometimes unnecessarily (theme or plugin). It can be avoided.
Durations are defaults and may change with configuration. This page describes a cookie; it is not legal advice.
