Sumsub Identity Authentication

Biometric authentication lets you verify customer identities by comparing their 3D face maps to their photos in government-issued IDs.

Safer than a password

Intelligent face map cannot be manipulated or tampered with

Quick as a wink

Authentication takes around 3 seconds

Fully compatible

iOS, Android, mobile SDK, web SDK

3 simple steps to balancing friction and security


When an account is set up, Sumsub generates the user’s face map and acquires an image of his/her government-issued ID.


The system checks liveness and compares the 3D face map against the photo on the ID to confirm the identity of the user.


At subsequent login or transaction approval, the system acquires a new face map that is compared to the original one.
