Way to Lock and Unlock the Biometric Details of ‘Aadhaar Card’
Once you are on the UIDAI website, find and click on the ‘Lock/Unlock Biometrics’ link under the Aadhaar Services section. This link leads to a separate page titled Lock/Unlock Biometrics’.
Under the ‘Lock your Biometrics’ section, enter your 12-digit Aadhaar number and the security code in the specified fields.
An OTP or One-Time Password for Login will be sent to your registered mobile number, according to the UIDAI website.
Enter the OTP received on your registered mobile number in the respective field and click ‘Login’. “Registered Mobile Number is essential to avail this service. In case your mobile number is not registered with Aadhaar, visit the nearest Enrolment Centre/Mobile Update End Point,” the UIDAI said separately on its website.
Once logged in, enter the security code once again and click on ‘Enable’. Your biometrics will now be locked. “You would not be able to use Aadhaar-based biometric authentication for any service unless you ‘Unlock’ your biometrics,” the UIDAI portal added.
At the end of the process of enabling the lock, the UIDAI online tool displays the message: “Congratulation! Your Biometrics is locked. You will not be able to authenticate by using your fingerprint or iris. You can unlock biometrics temporarily for any authentication requirements. You can also disable the Locked Biometrics But before that you will be required to login using your Aadhaar.”
