How to lock Aadhaar card biometrics?

You can lock your Aadhaar biometrics online through the official UIDAI website or the mAadhaar app. Visit the myAadhaar portal, log in using your Aadhaar number and the OTP sent to your registered mobile number, and select the Lock/Unlock Biometrics option. Confirm your choice to secure your fingerprint, iris, and face data. Alternatively, use the mAadhaar app’s biometric settings to enable the lock. This feature prevents unauthorized biometric authentication and enhances your privacy.
