What is multi-accounting?
Multi-accounting (also called multi-accounting fraud or farmed accounts) is the creation of many user accounts by the same person, household, or device to bypass limits, harvest promotions, or layer payments.
Signals that actually work
Shared device fingerprints, reused IPs, signup velocity, and recycled payment instruments identify account clusters. Review a new registration when its device is already linked to several customers.
How Naiza applies it
Naiza flags devices linked to multiple customer accounts and supports fingerprint lists. Combine those links with registration velocity and tune named thresholds for your product.
Review shared-device context
Do not BLOCK every family iPad. Use REVIEW, step-up, or limits first. Promo abuse and mule networks look similar until an analyst sees the cluster.
Frequently asked questions
Answers about screening, risk signals, and Naiza integration.
What is multi-accounting in fintech?
It is one actor operating many accounts, usually to farm bonuses, evade KYC limits, or move funds through mule-like structures.
How do you detect multi-accounting?
Attach a stable device id and customer external id to signup and login events, then rule on devices linked to many customers plus signup velocity.
Is multi-accounting the same as account takeover?
No. ATO hijacks an existing account. Multi-accounting creates many accounts. Both use device context, with different event types.
