By locking, users can lock their 12-digit Aadhar number instead use the 16-digit Virtual Identification (VID) whenever they need the same for authentication. It is to be noted that one the Aadhaar number is locked, a user cannot use the same for any kind of authentication by using UID, UID Token & ANCS Token for Biometric, Demographic & OTP Based authentication.
