In today’s digital age, securing your Aadhaar card is vital. This 12-digit unique ID, issued to all Indian residents including children, is linked to critical biometric data like fingerprints, iris scans, and facial recognition. Any misuse of this data can lead to serious consequences. That’s where the biometric lock feature comes in—a simple but effective security tool that protects your Aadhaar information from unauthorized use.

Secure Your Aadhaar: Step-by-Step Biometric Lock Guide
Activating the biometric lock ensures that no one can access or use your biometric data—such as for SIM card verification, banking, or other identity checks—without your consent. You can enable or disable this lock anytime via the UIDAI portal, mAadhaar app, or even through SMS. With Aadhaar now linked to PAN cards, bank accounts, voter IDs, ration cards, and mobile numbers, the potential for misuse has increased. Locking your biometrics adds a strong layer of protection and puts you in control of Aadhaar-linked transactions or verifications.
Steps to Lock Aadhaar Biometrics Online
To begin, generate a Virtual ID (VID) from the official UIDAI website using the ‘VID Generator’ option. Once you have your VID, follow these steps:
- Visit the UIDAI myAadhaar portal.
- Click on the ‘Lock/Unlock Aadhaar’ option.
- Read the instructions and click ‘Next’.
- Enter your VID, name, PIN code, and captcha, then click ‘Send OTP’.
- Enter the OTP received on your registered mobile number to complete the process.
Locking your Aadhaar biometrics is not just a recommendation—it’s a critical step in safeguarding your digital identity in an increasingly interconnected world.
Summary:
Locking your Aadhaar biometrics protects your sensitive data from misuse in digital transactions like banking or SIM verification. Easily activated via the UIDAI portal, app, or SMS using a Virtual ID (VID), this feature adds a crucial security layer, ensuring only you control access to your biometric information.
