Why multi-account prevention

One Face, One Contract — starting at registration.

Documents can be forged. Emails are free. Devices are shared. The only thing a fraudster can't duplicate is their face. Multi-Account Prevention runs a 1:N biometric search at the moment of sign-up, cross-referencing the new face against every existing record in your base. If this person already has an account — they don't get a second one.

No rules to configure. No velocity checks to tune. A deterministic answer based on biometric uniqueness.

In seconds, Multi-Account Prevention answers what traditional onboarding can't:
01
Has this person already registered under a different identity?
02
Is this the same face behind multiple accounts?
03
Is this a bot-driven or mass-created account?
04
Is this registration part of a coordinated fraud ring?

Capabilities

Behind the seamless experience.

Also supports retroactive base cleanup — ingest your historical selfie base to detect duplicates already in your system.

Liveness

Step one:

Confirms a real person is present at the moment of registration. Blocks bots, deepfakes, and non-human input before the biometric search even begins.

Multi accounts 1:N

Step two:

Performs a segmented biometric search across your entire registration base. Cross-references the new face against all records in the same segment. If the biometric is already linked to a different account — it's flagged before the registration completes.
