Now, lock your Aadhaar number for more privacy. Here’s how you can do it

New Delhi: In order to strengthen the privacy and security of Aadhaarcard holders, Unique Identification Authority of India (UIDAI) has introduced another feature which allow individuals to loch their Aadhaar number. Once you have locked the Aadhaar number, any authentication using Aadhaar number will not be permitted.

Once the Aadhaar number is locked, you will have to use the 16.digit Virtual ID called VID to authenticate yourself for any KYC services. You will be able to use your Aadhaar number for authentication only after unlocking it.

It may be noted that you need to generate your VOD before locking your Aadhaar number. It can be generated from either UIDAI’s website or through an SMS. Not that in order to generate VID through SMS, your mobile number must be registered with UIDAI.
