Fake Account Prevention
Stop bulk and synthetic account creation with device, phone and behavioural verification at registration.
The challenge
Fake accounts are used to abuse promotions, launder reputation on marketplaces, or provide throwaway identities for further fraud. Because these accounts are frequently created at scale by scripts or click farms, organisations need verification that raises the cost of mass registration without penalising genuine new customers with excessive checks.
Key capabilities in this use case
Phone and device verification
Require a verified phone number or recognised device before an account is fully activated.
Duplicate and pattern detection
Flag registrations sharing device fingerprints, network ranges or timing patterns typical of bulk creation.
Passkey binding
Tie each account to a device-bound passkey, making it harder to script large numbers of interchangeable accounts.
Graduated trust levels
Limit new-account capabilities until verification steps are completed, reducing the value of a fake account.
Core capabilities
Registration rules engine
Detects and flags suspicious sign-up patterns.
Phone verification
Confirms ownership of a real, reachable phone number.
Passkey binding
Anchors accounts to a specific verified device.
Risk-based activation
Delays full account privileges pending verification.
Blocking a promotional-abuse campaign
A loyalty programme notices a surge of new sign-ups redeeming a new-customer bonus, many originating from a small cluster of device fingerprints and IP ranges. With Authsignal's rules engine, registrations matching this pattern are automatically required to complete phone verification and passkey enrolment before the bonus is credited, rather than being granted instantly. The scripted registrations fail to complete this step, since they lack real phones or devices to bind, while genuine new customers pass through the verification in moments. The programme's fraud losses from the campaign drop sharply within days of the rule going live.
