UIDAI enabling multi-modal authentication, facilitating periodic updation of details and strengthening infrastructure to mitigate authentication-related issues

**Executive Summary** This report outlines measures taken by the Unique Identification Authority of India (UIDAI) to strengthen Aadhaar infrastructure and mitigate authentication failures, as presented in the Rajya Sabha on March 27, 2026. The document highlights the transition to multi-modal authentication and the periodic updating of holder details to ensure the seamless delivery of benefits across more than 3,100 government schemes. It emphasizes legal protections under the Aadhaar Act, 2016, which mandate that no eligible beneficiary be denied services due to technical authentication issues. **Key Points / Main Content** * **Aadhaar’s Scale and Welfare Impact** * Maintains records for approximately 134 crore live Aadhaar holders and has processed over 17,000 crore authentication transactions. * Supports over 3,100 Direct Benefit Transfer (DBT) schemes and 360 public services. * Eliminates duplicate or ineligible beneficiaries, ensuring transparent and leak-proof delivery of government benefits. * **Platform Features and Privacy** * Provides a digitally verifiable identity for sectors including banking, telecom, credit, and insurance. * Operates as a purpose-agnostic platform; UIDAI does not collect, retain, or maintain the specific purpose of authentication carried out by external entities. * **Mitigation of Authentication Issues** * Identifies causes of failure such as connectivity issues, biometric/demographic mismatches, invalid OTPs, and device-related technical reasons. * Addresses grievances in a time-bound manner through coordination with respective scheme-implementing Ministries and Departments. * Implements multi-modal authentication, including biometric, OTP, and face authentication, to improve reliability. * **Legal Safeguards for Beneficiaries** * Cites the Aadhaar Act, 2016, which prohibits the denial of welfare benefits to eligible beneficiaries due to a lack of Aadhaar or authentication failure. * Requires the provision of alternate and viable means of identification in cases where authentication cannot be completed. **Impact Analysis** **Aadhaar Number Holders (Citizens)** **Impact** Holders benefit from a trusted digital identity that enables seamless access to government and private sector services. They are protected by law from losing benefits due to technical failures. **Action Required** Holders are encouraged to participate in the periodic updation of their biometric and demographic details to ensure authentication remains successful. **Scheme-Implementing Ministries and Departments** **Impact** These entities achieve higher efficiency and accountability in governance by using Aadhaar-bank linkages for secure benefit transfers. **Action Required** They must coordinate with UIDAI to resolve authentication grievances in a time-bound manner and ensure alternate identification methods are available to prevent the denial of services. **Unique Identification Authority of India (UIDAI)** **Impact** The authority is responsible for managing the world’s largest biometric system and ensuring its infrastructure can support high-volume transactions. **Action Required** UIDAI must continue strengthening authentication infrastructure and enabling diverse authentication modes (biometric, OTP, and face) to reduce failure rates.
