The fingerprint method is only used if the user's browser does not accept cookies or Anonymized tracking is activated.
When a user accesses the website, the pixel checks whether an Ever ID/cookie exists. If this is not the case, a new Ever ID is generated and a new cookie is stored. If the user blocks cookies, an Ever-ID is generated, but no cookie can be set. Instead, a fingerprint ID (FEID) is formed.
The syntax for Ever IDs of users without cookies follows the same rules so that the evaluation in the frontend is equally possible (see End Devices Visitor IDs).
The fingerprint ID is formed from a hash of the IP and user agent. It is only used to hold the current session together. It is only stored during session and deleted afterwards.
The visitor is not recognized during a new session, even if the IP and user-agent are identical.
The fingerprint ID cannot be viewed via the frontend or the raw data.
