UIDAI launches mAdhaar App : All you need to know

It comes with a biometric locking/unlocking feature to secure the personal data. After downloading the app, you have to set up a password followed by entering your 12-digit Aadhaar number.

The app will then send an SMS from your registered mobile number for verification. Once a user enables the locking system, the app remains locked till he/she chooses to either unlock it  or disable the locking system.

Moreover, the app also has a “TOTP generation” (Time-based One-Time Password) process which can be used instead of SMS based OTP. Users can update their profiles too but only after successful completion of the request.
