What FingerprintJS can do for your paywall

Anonymous user identification

Every visitor to your website is assigned a permanent visitorID that can be used to identify visitors across browsing sessions and enforce your paywall limits.

Incognito mode detection

Catch even your sneakiest of visitors trying to evade paywalls through incognito or private browsing mode.

Geolocation

Capture detailed country, city, geoposition and timezone to better target and gate content to your visitors.

GDPR and CCPA compliant

FingerprintJS Pro is GDPR and CCPA compliant for use in fraud detection. For this use case, no visitor consent is required.
