The Unique Identification Authority of India (UIDAI) has launched the Aadhaar Face Authentication SDK (Software Development Kit) and Aadhaar Face Authentication Sandbox at the Global Fintech Fest 2026.
The new tools are aimed at making it easier for banks, fintech companies, insurance companies, brokerage firms, government departments and other ecosystem partners to integrate, test and deploy Aadhaar Face Authentication within their digital applications.
The initiative is particularly significant for the BFSI sector, where Aadhaar Face Authentication can support seamless identity verification and RBI-mandated multi-factor authentication requirements.
Aadhaar Face Authentication Can Now Be Integrated Into Mobile Apps
The newly launched Aadhaar Face Authentication SDK brings UIDAI’s Face Authentication capability directly into native Android and iOS applications.
One of the most important changes is that users can complete Aadhaar Face Authentication within the application of the service provider itself.
Previously, a user seeking to complete Aadhaar Face Authentication could require the separate FaceRD app to be installed on the device. This created an additional step in the onboarding process.
With the new SDK, a customer can potentially download only the banking, insurance, broking or other relevant application and complete the Aadhaar Face Authentication process within the same app.
This is expected to create a simpler and more seamless digital onboarding journey.
How the Aadhaar Face Authentication SDK Works
The SDK has been designed as a ready-to-use integration solution for ecosystem partners.
It incorporates several security and authentication capabilities, including:
- AI/ML-based liveness detection
- Anti-spoofing capabilities
- Secure handling of authentication data
- Encryption of authentication data
- Compatibility with consumer smartphones
- Integration with native Android and iOS applications
These capabilities are intended to help organisations deploy Face Authentication-enabled services while maintaining a secure authentication environment.
What is the Aadhaar Face Authentication Sandbox?
Alongside the SDK, UIDAI has introduced the Aadhaar Face Authentication Sandbox.
The Sandbox provides organisations with a secure and controlled testing environment in which developers and quality assurance teams can integrate and validate the Face Authentication journey before moving to production.
The testing environment allows organisations to evaluate different stages of the authentication process without requiring external biometric hardware.
Key Features of the Sandbox
The Sandbox enables testing of several important stages, including:
- User provisioning
- User consent
- Face capture
- Liveness checks
- Authentication
- Error handling
- Response validation
Developers can also test various failure and security scenarios.
These include:
- Invalid digital signatures
- Network interruptions
- Authentication timeouts
- Spoofing attempts
Such testing can help organisations identify technical and integration issues before deploying Face Authentication services to customers.
Simplifying the Digital Onboarding Journey
The launch addresses a long-standing requirement of the banking and fintech ecosystem for a smoother authentication experience.
Under the earlier model, users could require both the service provider’s application and the separate Aadhaar FaceRD application for certain Face Authentication journeys.
This meant that customers had to:
Download service provider app → Install FaceRD app → Complete Face Authentication
The SDK aims to simplify this process by allowing Face Authentication capabilities to be integrated directly into the service provider’s application.
The intended experience becomes:
Download one app → Complete Aadhaar authentication within the app
This can reduce friction during digital customer onboarding and potentially improve completion rates for authentication-dependent services.
Benefits for Banks, Fintechs and Other Organisations
The new SDK and Sandbox are expected to provide significant benefits to organisations operating in the digital identity and financial services ecosystem.
Simpler Customer Experience
Customers can complete authentication without switching between multiple applications.
Faster Integration
The ready-to-use SDK is intended to simplify integration for ecosystem partners.
Improved Testing
The Sandbox gives developers and QA teams a controlled environment to test the complete authentication journey.
Enhanced Security Testing
Organisations can evaluate liveness detection, anti-spoofing and different failure scenarios before production deployment.
Wider Digital Adoption
The simplified authentication journey can support wider adoption of Aadhaar-enabled digital services.
UIDAI’s Face Authentication Ecosystem Has Expanded Rapidly
UIDAI’s indigenous AI/ML-driven Face Authentication technology was launched in 2021.
According to UIDAI, the technology has now processed more than 500 crore transactions and has been adopted by nearly 200 entities.
These include:
- Union Government ministries and departments
- State Governments
- Banks
- NBFCs
- Telecom operators
- Brokerage firms
- Certifying authorities
The technology also received the Prime Minister’s Award for Excellence in Public Administration 2023 under the Innovation category.
Where Aadhaar Face Authentication is Used
Aadhaar Face Authentication has already become part of several government and digital service ecosystems.
Its applications include:
Digital Life Certificate
Pensioners can use Face Authentication for submission of their Digital Life Certificate through Jeevan Pramaan.
Ayushman Bharat
The technology is used for beneficiary onboarding and authentication.
Direct Benefit Transfer
Face Authentication supports authentication under various DBT schemes.
Aadhaar-Enabled Payments
It can also be used in authentication processes associated with Aadhaar-enabled payment services.
SIM Activation
Face Authentication can support SIM activation through e-KYC.
Government Schemes
Authentication is used for beneficiaries associated with schemes such as:
- PM e-Drive
- PM Awas Yojana
- PM Kisan
The expanding range of applications demonstrates the growing role of digital identity authentication in government and financial services.
UIDAI Launches Playbook for BFSI Onboarding
UIDAI also unveiled a “Playbook on Ease of Onboarding” during the event.
The playbook is intended to guide BFSI entities seeking to join the UIDAI authentication ecosystem.
It is designed to assist organisations with onboarding for identity verification involving:
- Customers
- Employees and staff
- Business partners
- Other stakeholders
The initiative is expected to make the onboarding process easier for financial sector organisations seeking to use UIDAI authentication services.
Industry Partners Support SDK Development
Ecosystem partners played an important role in developing and validating the Aadhaar Face Authentication SDK.
According to UIDAI, partner feedback during testing helped refine the SDK and complete its Proof of Concept (PoC).
Kotak Mahindra Bank, Bajaj Finance Limited and Airtel Payments Bank successfully completed the PoC for testing the SDK and emerged as early adopters in their mobile applications.
Motilal Oswal Financial Services Limited and Poonawalla Fincorp participated as early users of the Aadhaar Face Authentication Sandbox and contributed to its testing and validation.
A Significant Step for Digital Identity and Fintech
The launch of the Aadhaar Face Authentication SDK and Sandbox represents an important development in India’s digital authentication ecosystem.
By enabling Face Authentication to be integrated directly into Android and iOS applications, UIDAI is seeking to make the user journey simpler while giving organisations better tools for development, testing and deployment.
For the banking, financial services and insurance ecosystem, the ability to offer authentication within a single application could reduce onboarding friction and create a more convenient customer experience.
At the same time, the Sandbox provides developers with an environment to test authentication, security and failure scenarios before production deployment.
Conclusion
The launch of the Aadhaar Face Authentication SDK and Sandbox at Global Fintech Fest 2026 strengthens India’s digital identity infrastructure by bringing Face Authentication closer to the applications that citizens already use.
The SDK can enable banks, fintechs, government departments and other organisations to integrate secure, AI/ML-based Face Authentication directly into their Android and iOS applications, while the Sandbox provides a controlled environment for testing and validation.
With more than 500 crore Face Authentication transactions already processed and adoption across nearly 200 entities, the latest initiative could further expand the use of Aadhaar-based facial authentication across India’s digital services ecosystem.
Most importantly, the move seeks to make authentication simpler for users, easier for organisations to integrate and more efficient to test, supporting the continued evolution of India’s digital-first financial and public service ecosystem.
