Aadhaar is one of the most important identity documents in India, used for various financial transactions, SIM card issuance, and government services. However, with increasing cases of Aadhaar misuse, securing your biometric data has become essential. The Unique Identification Authority of India (UIDAI) offers a Biometric Lock feature that prevents unauthorized access to your fingerprints, iris scans, and facial data.

This security feature ensures that no one can use your Aadhaar for authentication without your consent. You can lock or unlock your biometrics anytime using the UIDAI portal, mAadhaar app, or even via SMS. Here’s how you can do it.
