How Do You Lock a Biometric?

You can lock your Aadhaar biometrics data using the mAadhaar app.

Here's a breakdown of the process based on the provided information:

1. Download the mAadhaar app: Begin by downloading the official mAadhaar application.
2. Register your Aadhaar number: After installation, register your Aadhaar number within the app.
3. Enter OTP: You'll receive a One-Time Password (OTP) on your registered mobile number. Enter this OTP into the app for verification.
4. Set a four-digit PIN: Create a secure four-digit PIN to access the mAadhaar app and its features.
5. Lock Biometrics: Within the app, locate the "Lock/Unlock Biometrics" option and choose to lock your biometrics.

Locking your biometrics prevents their use for authentication purposes until you unlock them again. This can enhance the security of your Aadhaar data.
