Lock/Unlock Aadhaar Biometric Data Online

Aadhaar has emerged as a highly reliable government document that serves as both proof of identity and proof of address. Recently, concerns have been raised regarding the security of Aadhaar, prompting UIDAI to introduce the option of locking and unlocking Aadhaar biometric data online. This service aims to assist users in safeguarding their biometric information from potential misuse. It is important to note that numerous agencies require applicants to authenticate their details using the Aadhaar biometric verification feature.

There are two ways to lock and unlock Aadhaar biometric data online: through UIDAI’s portal and the mAadhaar app, which is the official app of UIDAI. Both methods are secure and accessible 24×7, enabling individuals to protect their Aadhaar biometrics effectively.

How to Lock Aadhaar Biometrics Online

To lock or unlock your biometrics online, follow these simple steps:

1. Go to the UIDAI portal and select “Lock/Unlock Biometrics” from the Aadhaar Services section.

2. Enter your 12-digit Aadhaar number and security code, then click “Send OTP.”

3. Check your registered mobile number for the OTP and enter it on the website.

4. Click “Login” to access the biometric locking feature.

5. Enter a 4-digit security code and click “Enable” to lock your biometrics.

6. Remember that you will need to unlock your biometrics if you want to access them again in the future.
