Here's how you can lock/unlock your Aadhaar number

In a bid to further strengthen the privacy and security of Aadhaar, the Unique Identification Authority of India (UIDAI) has introduced a new feature that enables users to lock/unlock their Aadhaar number.

Once locked, your Aadhaar number cannot be used for authentication services.

To facilitate authentication, you'll have to generate your 16-digit Virtual ID for Aadhaar.
