Aadhaar Authentication refers to the process by which the Aadhaar number along with the demographic information or biometric information of the holder is cross-checked by the Central Identities Data Repository (CIDR) on the request of a service provider like a bank or a telecom operator for ID proof. This helps reduce the time taken to fill out individual forms and a long verification process.

This is called Aadhaar authentication history which can be accessed by logging into UIDAI website.

3) You will now be able to see a detailed list of Aadhaar authentication requests for your ID. This list will tell you the date, time, and type of authentication request.
