From availing of government schemes to obtaining a driving license, an Aadhaar card facilitates the process of verifying an individual’s identity. It contains a unique Aadhaar number which is issued by the Unique Identification Authority of India (UIDAI). Besides this, the card holds our crucial personal information including our biometrics, such as fingerprints, iris, and facial images.
Now, amid growing concerns around data privacy and security, it becomes important that you ensure the safety of your data, especially biometrics, stored in the Aadhaar card. Cybercriminals and fraudsters can misuse biometric details and carry out unauthorised authentication.
However, UIDAI provides a feature through which you can lock your biometric details. Anyone with a valid Aadhaar card can use the feature to lock and temporarily unlock their biometrics. This, according to UIDAI, ensures the confidentiality of the biometric details of an individual.
Once the biometric data is locked, the Aadhaar card holder will no longer be able to use the details for authentication. In case a person tries to use any authentication service using Aadhaar when the biometrics is locked, a specific error code 330 will indicate that the biometric details can’t be accessed.
Below are the steps you can follow to lock your Aadhaar biometric details
Step – 1 Visit the official website of UIDAI and click on My Aadhaar
Step – 2 Select Aadhaar Services and then choose Secure your Biometrics.
Step – 3 Click on Lock/Unlock Biometrics and enter your 12-digit unique Aadhaar number and a captcha verification code. Then select Send OTP
Step – 4 Enter the OTP received on your registered mobile number in the respective field and login
Step – 5 Proceed to click on Lock/Unlock Biometrics and press confirm
Step – 6 Your biometrics will be successfully locked
It must be noted that once you lock your biometrics, they remain inaccessible until you choose to either unlock them or disable the biometric lock.
