Why is FingerprintJS the #1 Choice For Account Sharing Prevention?

Catch account sharers where other tracking methods fail.

Mobile devices, infrequent logins, and privacy browsing make detecting account sharing difficult. An account can be misidentified as having multiple owners if their browsing behavior changes over time. Conversely, visitors can appear the same if not enough unique information is collected.

FingerprintJS overcomes these technical challenges by using state-of-the-art browser identification and machine learning techniques.

Generate unique visitorIDs

FingerprintJS uses browser fingerprinting, cookies, and other technologies including server-side detection techniques. By combining many identification methods, FingerprintJS can reach a higher level of accuracy than any other solution.

Ensure visitorIDs are stable over time

FingerprintJS uses fuzzy matching and other deduplication techniques. FingerprintJS Pro associates new browsing history with the correct visitorID even if some details about the visitor have changed.
