What the _hjSessionUser_ cookie does
Hotjar cookie that is set when a user first lands on a page with the Hotjar script. It is used to persist the Hotjar User ID, unique to that site on the browser. This ensures that behavior in subsequent visits to the same site will be attributed to the same user ID.
This cookie assigns a unique Hotjar User ID to visitors, ensuring subsequent visits to the same site are attributed to the same user.
The name ends in a part that changes from visitor to visitor or site to site, so this entry covers every cookie whose name starts with _hjSessionUser_.
Who sets it
Consent category: functional
Functional cookies remember a choice the visitor made, such as a language, a region or a layout preference. They are not essential, so visitors in the EU must be able to decline them, and a site should not set them before consent.
