Here’s how you can lock/unlock your Aadhaar data

In a bid to enhance security of users’ biometrics (fingerprints and iris data), and in order to avoid misuse of sensitive personal information, the Unique Identification Authority of India (UIDAI) launched a service, by which users can “lock/unlock” their biometric data.

There are mainly three ways to lock or unlock your Aadhaar data.
Here’s your step-by-step guide on how to do it.

Meth
od #1: Through the mAadhaar app

To follow this method, you’ll first have to install and log in to the UIDAI mAadhaar app.

At the bottom of the screen, click on Biometrics Unlock notification.
You’ll have to enter your mAadhaar password.

Once authenticated, your biometrics will be locked, and you won’t be able to do any transactions now.

To unlock your biometrics, follow the procedure again.


Method #2: Switching the toggle button in mAadhaar app

You can also use the toggle button in mAadhaar app to lock/unlock your biometrics. For this, click on the three dots icon on the top-right corner of the mAadhaar app. Then switch on/off the ‘Enable Biometrics Lock’ toggle button.

Method #3: Through the UIDAI website

On the UIDAI portal, click on ‘Lock/Unlock Biometrics’, under ‘Aadhaar services’ section.

You’ll be redirected to the biometrics locking section.
Once there, enter your 12-digit Aadhaar number (or UID), and the security code provided on the screen.

Subsequently, an OTP will be generated and sent via SMS to your Aadhaar-registered mobile number.

Enter the OTP and enable/disable the biometric lock, as per your requirements.


How the facility is beneficial
The biometric data of a user comprises their fingerprints and iris scans.
According to the UIDAI, the (lock/unlock) facility protects privacy and confidentiality of residents’ biometrics data.
The facility, by allowing the temporary locking and unlocking of one’s biometric information, ensures that the Aadhaar holder can’t use their biometrics for authentication, thus preventing potential misuse of information
