The Unique Identification Authority of India (UIDAI) has launched the “Face Auth SDK & Sandbox”, a software development kit and testing platform aimed at helping developers integrate Aadhaar-based face authentication into digital services.
The offering was unveiled on the second day of Global Fintech Fest (GFF) 2026 in Mumbai. It brings together ready-made software components and a controlled testing environment, enabling developers to build and test face authentication-based services before deploying them for users.
The new SDK is designed to simplify the technical process of integrating Aadhaar face authentication into digital platforms. Developers can use the software tools to incorporate face-based identity verification into their applications and services, while the sandbox allows them to test these integrations in a controlled environment before launch.
The initiative could help reduce the time, development effort and technical complexity involved in deploying face-based identity verification, particularly across fintech and other digital services.
