Engineering teams that want to build device-aware policies and join recognition to their own payment, identity or account data.
How the product works
Fingerprint provides a visitor identifier and Smart Signals about the client environment. Its documentation separates identification from signals such as VPN use, browser tampering and bot-related indicators. The integration connects client collection with server-side event retrieval.
From evidence to a decision
Choose it when a stable device-related identifier is a missing input to an existing risk system. Link the returned event to an authenticated user and the action being assessed. Keep a request or event reference so an analyst can distinguish the original observation from a later interpretation.
What to confirm before buying
Plan and platform affect the available signals. The free identification allowance does not establish unrestricted access to all web Smart Signals. Pro Plus and Enterprise offer different signal access; Android has a separate allowance described on the pricing page.
A useful first pilot
Test repeat visits across supported browsers and mobile platforms, then inspect signal availability and server-side retrieval. Measure collection failures separately from a successful check that reports no risk. Compare identity continuity with the account relationships your application records.
Strengths to evaluate
- Clear device identity focus
- Documented web and mobile integrations
- Server-side event retrieval for application workflows

FAQ
Does the free plan include every Smart Signal?
No. Verify the signal, platform and plan in the current documentation. The free identification allowance alone does not establish that coverage.
Does a matching device prove that two accounts belong to one person?
A device relationship is evidence to investigate. Shared devices and legitimate teams still require account context.
