How to Lock and Unlock your Aadhaar Biometrics?


Aadhaar has become one of the most trusted government documents, serving as both confirmations of identity and verification of address. The security of Aadhaar has recently been under fire, prompting UIDAI to enable the ability to lock/unlock Aadhaar biometric data online. This service is intended to assist users in preventing their biometric information from being misused in any way. It is worth mentioning that several agencies ask applicants to use the Aadhaar biometric authenticate facility to validate their information.

There are two ways to lock and unlock Aadhaar biometric data online: through the UIDAI portal and through the mAadhaar app, UIDAI’s official app.
