To lock a UID, the person must have a 16-digit VID number. If he/she does not already have a VID, they can obtain one using SMS or the UIDAI website (www.myaadhaar.uidai.gov.in).
A person is most concerned about the security and privacy of their data. Therefore, UIDAI provides a system for locking and unlocking Aadhaar numbers (UID) to increase the security of Aadhaar number and provide the individual more control. Residents can lock their UID (Unique Identification Number) using the UIDAI website (www.myaadhaar.uidai.gov.in) or the mAadhaar app.
If a person chooses this option, they will not be able to undertake any type of authentication using UID, UID Token, and VID (virtual ID) for biometrics, demographics, and OTP modalities.
