In India, an Aadhaar card is considered the most significant document for identifying yourself.

The fact that an Aadhaar number is unique and cannot be duplicated is the most crucial aspect that makes it secure. This is because each Aadhaar number is connected to the holder’s biometrics (fingerprints, iris scans, and photographs).

As the most crucial identity document, you must ensure that your Aadhaar details are never used without your authorization.

Since it is already so secure then why should you lock your biometrics, You might ask.

Importance of locking your Aadhaar Biometrics data

If someone has access to your biometrics, they have direct access to all your Aadhaar details. A person can easily get access to places where you have linked your Aadhaar card.

You cannot modify your fingerprint or Iris pattern of your eye in the same way that you can change a password.

Locking your biometrics ensures that even if a hacker tries to stealthily obtain your fingerprints (through everyday objects such as a door knob or a glass), they will not be able to use it to gain access to your Aadhaar details.

The UIDAI servers will simply deny access with an error code suggesting that you must first unlock your biometrics.
