You can now lock your Aadhar card

New Delhi, May 19: If you are worried about the privacy of your Aadhar card, don't be.

The Unique Identification Authority of India (UIDAI) has come up with a feature that will effectively put an end to your privacy concerns as it allows you to lock or unlock your Aadhaar number at your own sweet will.

Once your Aadhaar number number has been locked, it can't be used for authentication services through OTP, biometric, demographics or any other means.

However, even after you have locked your Aadhaar number, you will still be able to use it to authenticate yourself for KYC purposes.

In order to do this, you will have to use the Virtual ID (VID), which is a 16-digit random number issued by the UIDAI. This VID can be used instead of Aadhaar number to keep your private biometric data secure.

"VID is a temporary, revocable 16-digit random number mapped with the Aadhaar number. VID can be used in lieu of Aadhaar number whenever authentication or e-KYC services are performed. Authentication may be performed using VID in a manner similar to using Aadhaar number. It is not possible to derive Aadhaar number from VID," a statement on the official UIDAI website said.

However, if you want to use your original Aadhaar number after locking it, you will have to unlock it first.

Before you can lock your Aadhaar number, you will have to generate your Virtual ID from the UIDAI website or through SMS. For this, your mobile number must be registered with the UIDAI.

In order to lock your Aadhaar number, you will have to click on the 'My Aadhaar' option on the UIDAI website.

You will then have to click on the 'Lock/Unlock Biometrics' tab and log in with details asked on the "https://resident.uidai.gov.in/biometric-lock" page.

Here you will need to fill details like name, pin code, UID etc and select the 'Send OTP' option.

You will then receive an OTP on your registered mobile number which you will have to enter and click the submit button. After this, your Aadhaar number will be locked.

You can also lock your Aadhaar number through SMS by sending a message with 'GETOTP' and last four digits of your Aadhar number to 1947. You will soon receive an OTP on your mobile. 

Now, send another SMS containing 'LOCKUID' and last four digits of your Aadhar number and the OTP number. Your Aadhar will be locked once the SMS is sent.

In order to unlock your Aadhaar through SMS, you will have to send a message containing 'GETOTP' and last four digits of your virtual ID number. You will soon receive an OTP.

You will then have to send another SMS in the format - 'UNLOCKUID', last six digits of virtual ID number and the OTP.

Once this message is sent, your Aadhaar will be unlocked.
