Aadhaar Biometric Locking System enables residents to lock and temporarily unlock their biometrics. Once resident enables Biometric Locking system their Biometric remains locked up to the Aadhaar holder it is to.
As per UIDAI (the nodal agency for Aadhaar authentication), "Locked Biometrics ensures the Aadhaar holder will not be able to use their Biometrics (fingerprints / iris) for authentications thus preventing potential misuse." UIDAI allows Aadhaar card holders to disable as well as their biometric data on its website.
Here's a step-by-step guide for the same. But before you go ahead, remember that registered mobile number is essential to avail this facility online.
