The Unique Identification Authority of India (UIDAI) is strengthening Aadhaar authentication by enabling multi-modal verification, supporting periodic updates of details, and improving infrastructure to minimize authentication issues. Aadhaar, with around 134 crore active users, is the world’s largest biometric identity system, having completed over 17,000 crore authentication transactions.
Aadhaar serves as a foundational identity for delivery of government benefits and services. More than 3,100 Direct Benefit Transfer (DBT) schemes and 360 public services currently use Aadhaar authentication, ensuring targeted, transparent, and leak-proof delivery of welfare benefits while eliminating duplicate or ineligible beneficiaries.
Through Aadhaar-bank linkage, benefits are transferred directly and securely into beneficiaries’ accounts, enhancing governance efficiency and accountability. For individuals, Aadhaar provides a digitally verifiable identity, enabling access to services in banking, telecom, credit, insurance, and other sectors.
UIDAI emphasizes that Aadhaar acts as a purpose-agnostic platform, meaning it does not retain information about why authentication is carried out by government entities.
Given its scale, authentication failures can occur due to connectivity problems, biometric or demographic mismatches, invalid OTPs, device issues, or other technical reasons. UIDAI addresses such grievances in a time-bound manner in coordination with the relevant ministries.
To further improve reliability, UIDAI has implemented multi-modal authentication (biometric, OTP, and face verification), enabled periodic updates of biometric and demographic data, and strengthened infrastructure for seamless service delivery.
Importantly, under the Aadhaar Act, 2016, no eligible beneficiary can be denied welfare benefits due to Aadhaar-related issues. In case of authentication failure or non-assignment of Aadhaar, alternate identification methods are provided.
