Persistent Device ID for fraud prevention
Recognize devices over time and connect activity across sessions. Improve trust decisions without adding friction to good users. Block suspicious users before they can cause any harm to your platform, identifying them by continuous evaluation of the activity associated with the account’s persistent device ID.
Turn device identity into a trust layer
Link sessions across time
Build a stable device graph so you can identify repeat offenders and trusted users with high confidence.
Stop account takeovers
Detect risky logins by comparing the device fingerprint to a user’s known devices and historical behavior.
Prevent multi-accounting
Find clusters of accounts that share the same device to detect bonus abuse, referral fraud, and repeat signups.
A persistent device identifier helps you answer one question across every event: have we seen this device before, and what does its history suggest?
Attackers can rotate emails, phone numbers, IPs, and payment methods. Devices are harder to rotate consistently. A durable device layer lets you connect risk across signup, login, OTP, checkout, and incentives without relying on brittle cookies.
A practical rollout: start with signup and login, measure false positives, then expand to promotions and payouts. Use tiered enforcement so trusted devices stay low-friction and suspicious devices are stepped up.
