Unlocking biometric capabilities, specifically for your Aadhaar Unique Identification (UID), can be securely accomplished using a Time-based One-Time Password (TOTP) directly through the official UIDAI website. This method provides a robust way to regain access to your Aadhaar services after a biometric lock.
Understanding Aadhaar Biometric Lock and Unlock
The Aadhaar system, managed by the Unique Identification Authority of India (UIDAI), incorporates biometrics (fingerprints and iris scans) for secure identity verification. To enhance security and prevent potential misuse, Aadhaar holders have the option to lock their biometrics. When biometrics are locked, they cannot be used for authentication. Unlocking them means re-enabling this crucial authentication method, allowing you to use your fingerprints or iris scans for various services requiring Aadhaar verification.
Step-by-Step Guide: Unlocking Aadhaar UID with TOTP
Follow these straightforward steps to unlock your Aadhaar UID using TOTP:
- Visit the Official UIDAI Website: Navigate to the dedicated Aadhaar lock/unlock portal.
- Select the 'Unlock' Option: On the page, you will find radio buttons; select the "Unlock" radio button.
- Enter Latest VID: Provide your Latest Virtual ID (VID). The VID is a temporary, revocable 16-digit number mapped with your Aadhaar number, used for authentication without sharing your actual Aadhaar number.
- Input Security Code: Enter the displayed security code (captcha) into the designated field.
- Choose TOTP Option: Instead of selecting "send OTP," select the "TOTP" radio button. This signifies your intention to use a Time-based One-Time Password generated by the mAadhaar app on your registered mobile device.
- Click 'Submit': After entering all the required details and selecting TOTP, click on the "Submit" button.
Upon successful submission, your Aadhaar UID will be unlocked, allowing you to use your biometrics for authentication again.
Key Requirements for Unlocking
To successfully unlock your Aadhaar UID using TOTP, ensure you have:
- Access to mAadhaar App: The TOTP is generated via the official mAadhaar mobile application, which must be linked to your registered Aadhaar number.
- Latest Virtual ID (VID): This ensures you are unlocking the correct Aadhaar.
- Internet Connectivity: Required to access the UIDAI website.
