Stop fraud without the friction
The same visitor ID answers a different question in every flow. Open a case to see what the identification finds.
Spot a stolen password the moment it logs in from a browser the account never used, and let the real user in without friction.

-
Account takeover
Spot a stolen password the moment it logs in from a browser the account never used, and let the real user in without friction.
-
Multi accounting
See every account opened on one browser, so farmed and banned accounts surface before they cost you.
-
Bonus and promo abuse
Pay a welcome bonus once per device. A browser that already claimed it gets the regular sign up, without blocking the person.
-
Bots and credential stuffing
Stop scripts trying leaked passwords before the password is checked, and let good crawlers and declared AI agents through.
-
Payment fraud
Score a checkout before the payment goes out. Send the risky ones to 3-D Secure and let everyone else pay without friction.
-
Free trial abuse
Remember the browser, not the email. Someone back for a third trial gets the paid sign up instead.

Identical devices, like the same phone model on the same OS, can share a visitor ID. Treat a shared browser as a lead to review together with the other signals, never as proof by itself. Related
