What Is Aadhaar Biometric Lock?

• No one can authenticate using your fingerprints or iris scan

• Demographic and OTP-based authentication still works

• You can temporarily unlock biometrics whenever needed

Why You Should Lock Your Aadhaar Biometrics

• Prevent unauthorized authentication:: Stops anyone from misusing your biometrics without your knowledge

• Protection against fraud:: Even if your Aadhaar number is compromised, locked biometrics cannot be used

• You stay in control:: Unlock temporarily only when you need it, then lock again

• No cost involved:: The feature is completely free on both the UIDAI portal and mAadhaar app

Step 3: Enable Biometric Lock

• Select Lock to disable biometric authentication

• Confirm the action via OTP sent to your registered mobile number

• You will receive a confirmation message once biometrics are locked

Key Facts About VID:

• 16-digit temporary number

• Can be used wherever Aadhaar number is accepted for authentication

• Can be regenerated anytime (old VID becomes invalid)

• Agencies cannot derive your Aadhaar number from VID

What You Can See:

• Date and time of each authentication

• Type of authentication (biometric, OTP, demographic)

• Name of the requesting agency (AUA)

• Whether authentication was successful or failed

Benefits of TOTP:

• Works even when SMS delivery is delayed

• More secure than SMS OTP (generated locally on your device)

• No dependency on mobile network for OTP delivery

• Useful in areas with poor network coverage
