When a resident locks their Aadhaar, they cannot perform any authentication using UID, UID Token, or VID(Virtual ID) for biometrics, demographic information, or OTP modalities.
For residents, safeguarding personal data is a significant concern. To enhance the security of Aadhaar numbers and give residents greater control over their privacy, the Unique Identification Authority of India (UIDAI) – responsible for issuing the 12-digit personal identification number known as Aadhaar based on biometric and demographic data – provides a system for locking and unlocking the Unique Identification (UID) Number or Aadhaar number online. A string of online services provided by the UIDAI enable Aadhaar subscribers to lock or unlock their UIDs website through the myAadhaar portal (www.myaadhaar.uidai.gov.in) or the mAadhaar mobile app.
What does locking an Aadhaar mean?
When a resident locks their Aadhaar, they cannot perform any authentication using UID, UID Token, or VID(Virtual ID) for biometrics, demographic information, or OTP modalities. To unlock the UID, residents can use their latest VID via the UIDAI website or the mAadhaar app.
It is only after unlocking that the resident can resume using the UID, UID Token, and VID for authentication.
