UIDAI-Aadhaar: Aadhaar Number is the new User Name for Authentication of an Indian individual


To reduce leakages or to increase security levels, be it in physical buildings or computer networks, Authentication is the preferred mode. Authentication is the process wherein the individual conforms who she/he claims to be.

The ‘Authentication’, process is not a modern process but was prevalent even in ancient times. Only the methods of ‘Authentication’ have changed.

The latest ‘Authentication’, tool is the Aadhaar based mode. In modern world, ‘Authentication’, revolves around a UserName and Password.

In the UIDAI-Aadhaar Authentication model, the USERNAME is the ‘Aadhaar Number’, and the PASSWORD is either the OTP (One Time Password) or Iris or fingerprint.

At present, UIDAI-Aadhaar Authentication offers the following 5 types:

Type 1 Authentication: Through this offering, service delivery agencies can use Aadhaar Authentication system for matching Aadhaar number and the demographic attributes (name, address, date of birth, etc) of a resident.

Type 2 Authentication: This offering allows service delivery agencies to authenticate residents through One-Time-Password (OTP) delivered to resident’s mobile number and/or email address present in CIDR.

Type 3 Authentication: Through this offering, service delivery agencies can authenticate residents using one of the biometric modalities, either iris or fingerprint.

Type 4 Authentication: This is a 2-factor authentication offering with OTP as one factor and biometrics (either iris or fingerprint) as the second factor for authenticating residents.

Type 5 Authentication: This offering allows service delivery agencies to use OTP, fingerprint & iris together for authenticating residents.

To reduce load on the Aadhaar Servers, the Aadhaar Number is part of all forms of the above 5 authentication models i.e the operation is reduced to 1:1 match.

This means as mentioned above, the Aadhaar Number is the Username only, and not the Password.
