Why use Matomo with Fingerprint

Matomo uses cookies to identify visitors. When cookies are not available or visitors use incognito mode, Matomo will create multiple visitors for one actual visitor. Depending on your website traffic, this can pose a significant issue as it will incorrectly count your visitors. Fingerprint makes it easy to identify your website visitors with Matomo by linking them to the Fingerprint’s visitorID value. Matomo has a limitation, which doesn’t allow to replace their cookie-based identifier, but it has a userID functionality, that can be used to link Matomo visitors with Fingerprint visitors. To do this, you would need to use a slightly different configuration for Matomo JavaScript tracking client.
