Agencies can efficiently perform online identity checks using several straightforward methods. The various ways in which Aadhaar card authentication is conducted include the following:

Biometric-Based Authentication

Biometric authentication identifies individuals based on unique biological characteristics like fingerprints, iris patterns, voice recognition, or DNA. This method compares your biometric details with the records in the CIDR to establish your identity.

Demographic Authentication

Demographic authentication involves confirming basic personal information, such as your name, address, gender, contact details, and date of birth, that you submitted during Aadhaar registration. This information is linked to your Aadhaar number and checked against the data available in the Central Identities Data Repository (CIDR) for verification.

OTP-Based Authentication

An OTP (one-time password) is a temporary, unique code used for a single transaction or login session. To authenticate your identity for Aadhaar-linked services, you will need to request an OTP from the service provider’s app or platform. Then, enter your Aadhaar number and the OTP to verify your identity.
