The Indian government has taken a number of steps to improve Aadhaar confidentiality, as well as to safeguard Aadhaar security and avoid its misapplication. Locking Aadhaar implies using the 16-digit Virtual ID (VID) instead of your 12-digit Aadhaar for all forms of verification. And once Aadhaar is locked, individuals are unable to perform biometric, demographic, or OTP-based authentication using the UID, UID Token, or ANCS Token.
