In a bid to enhance security of users' biometric data, and prevent potential misuse of sensitive personal information, the Unique Identification Authority of India (UIDAI) launched a service, by which users can "lock/unlock" their biometrics.
There are mainly three ways to lock or unlock your Aadhaar data.
Here's all you need to know about it, and a step-by-step guide on how to do it.

The biometric data of a user comprises their fingerprints and iris scans.
According to the UIDAI, the said (lock/unlock) facility protects privacy and confidentiality of residents' biometrics data.
The facility, by allowing the temporary locking and unlocking of the biometric information, ensures that the Aadhaar holder cannot use their biometrics for authentication, thus preventing potential misuse of Aadhaar-registered information.

Post the September 26, 2018 Supreme Court verdict concerning authentication of Aadhaar, there has been much confusion with respect to services where Aadhaar is mandatory and where not.
Aadhaar is no longer mandatory for services such as opening bank accounts, telecom services, and school admissions/entrance tests.
However, it is still necessary for availing government welfare schemes, and filing I-T returns (if PAN isn't used).
