What the _sp_id. cookie does
Stores user information that is created when a user first visits a site and updated on subsequent visits. It is used to identify users and track the users activity across a domain. This cookie stores a unique identifier for each user, a unique identifier for the users current session, the number of visits a user has made to the site, the timestamp of the users first visit, the timestamp of their previous visit and the timestamp of their current visit.
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 _sp_id..
Who sets it
Consent category: analytics
Analytics cookies measure how a site is used, in aggregate: pages seen, sessions, where visitors came from. Under the GDPR they need consent before they are set, and Google Consent Mode can model what is lost when visitors decline.
