For an Aadhaar number holder, security and privacy of personal data is always a primary concern. To strengthen the security of his/her Aadhaar number and to provide control to the Aadhaar number holder, UIDAI provide a mechanism of locking and unlocking Aadhaar number (UID).
Aadhaar number holder can lock his or her Aadhaar (UID) via UIDAI website (www.myaadhaar.uidai.gov.in) or through mAadhaar app.
By doing this Aadhaar number holder cannot perform any sort of Authentication using UID, UID Token & VID for Biometrics, Demographic & OTP modality
If Aadhaar number holder wants to unlock UID he/she can do so by using latest VID, through UIDAI website or mAadhaar app.
After unlocking Aadhaar (UID), Aadhaar number holder can perform authentication using UID, UID Token & VID.
